...Introduction Humans share a mutual ancestors with other organisms. This mutual ancestor that humans share with other organisms including rice that lived about 1.6 billion years ago. Chimpanzees and bonobos are our closet living relative. Researchers were able to come to this conclusion by comparing the genomes of chimpanzees and bonobos to the genome of humans. In this paper I will discuss why all organisms are related to each other, including humans. I will do this by using natural selection as a mechanism for evolution. Natural selection as a mechanism for evolution explains how organisms have changed over time to adapt to their environment. I will also provide the percent of relatedness in terms of nucleotide sequence. I will also discuss the Human genome project and its importance. The benefits of the human genome project extend far beyond determining who our closest ancestor is and how closely humans are related to mice and other organisms. In this paper I will also look at the technology that has been developed to enhance the findings the Human Genome Project. Humans Are Related To Other Organisms Humans share about 99% of our DNA with chimpanzees and bonobos. DNA (deoxyribonucleic acids) is the molecule that makes up an organism’s genome. DNA is located in the nucleus of eukaryotic cells and is found in the nucleoid of prokaryotic cells. DNA consist of genes which are instructions to make molecules called proteins. DNA’s serves a significant purpose...

...population, natural resources, and as recently as (2004) human genetics under the research name (The Human Genome Project). Much like a puzzle the shapes, patterns and order of human DNA have been plotted by scientists’ and have been transformed into a map like none other. The Human Genome Project has been referred to as “one of the great feats of exploration in history- an inward voyage of discovery rather than an outward exploration of the planet or the cosmos.” Genetic mapping will not cure genetic diseases by itself, but it is a critical tool in expanding scientists’ understanding of the role gene mutation and deletion play in causing complex diseases and disorders. From this understanding, strategies to develop cures and preventive measures evolve. Inherited genetic variation has a key but as of yet largely uncharacterized role in human disease. Genome mapping has advanced the screening of genetic diseases with more than 39,000 genetic tests currently in use in the, molecular, chromosomal and biochemical genetic fields, according to GeneTests, a database supported by the federal government. The results of genetic tests can confirm or rule out suspected genetic conditions or help determine a person’s chance of developing or passing on a genetic disorder. The medical insight genome mapping can provide will undoubtedly change the way we think...

...million Americans are in someway affected by alcoholism. Current prescribed medications can only do so much. The solution lies in finding the roots of the problem. It has been believed that alcoholism runs down family lines, generation after generation. Is there scientific truth to this? Could the addiction be embedded in the human genome? John Crabbe and Justin Rhodes invite you to study their 10 years of research. Taking mice and making them alcohol-dependent, studying their human-like tendencies; alcohol tolerance, withdrawal symptoms, and voluntarily drinking alcohol and in some instances doing extra work for the tipple intoxicant. Using methods of genetic engineering, gene expression profiling and quantitative locus mapping, the two colleagues are equipped to haunt down the chromosome and location where alcoholism lay. With the genome being so outstandingly large, can a gene for alcoholism be merely pinpointed? After years of trying the scientists come closer then anyone before them, but it is Dr. Tamara J. Philips who furthers the journey and exploration. New strategies are needed to stop and treat this disease; a location in the genome is imminent upon us. For centuries, alcoholism has been destroying many lives. The act of an addiction to something as harmful has alcoholism demolished families, relationships, and one’s own body. Alcohol on average is responsible for 100,000 deaths in America per year, whether it is from drunk-driving accidents, health...

...The Human Genome Project (HGP) was one of the great feats of exploration in history - an inward voyage of discovery rather than an outward exploration of the planet or the cosmos; an international research effort to sequence and map all of the genes - together known as the genome - of members of our species, Homo sapiens. The Human Genome Project was started in 1990 with the goal of sequencing and identifying all three billion chemical units in the human genetic instruction set, finding the genetic roots of disease and then developing treatments. It is considered a Mega Project because the human genome has approximately 3.3 billion base-pairs. With the sequence in hand, the next step was to identify the genetic variants that increase the risk for common diseases like cancer and diabetes. It was far too expensive at that time to think of sequencing patients’ whole genomes. So the National Institutes of Health embraced the idea for a "shortcut", which was to look just at sites on the genome where many people have a variant DNA unit. The theory behind the shortcut was that, since the major diseases are common, so too would be the genetic variants that caused them. Natural selection keeps the human genome free of variants that damage health before children are grown, the theory held, but fails against variants that strike later in life, allowing them to become quite common. (In 2002 the National Institutes of Health started a $138 million project called the HapMap to catalog the...

...Life The Human Genome Project (HGP) began in 1990 with the primary goal of determining what makes up the human DNA, identifying the total genes, and mapping the human genome. The sequencing of the human genome is the largest undertaking in biological science, and is a huge achievement in the scientific community. The project was completed in 2003 and gave scientists the ability to read nature’s genetic blueprint of a human being. Those scientists and medical professionals who were excited about the HGP saw clearly how genomics would advance medicine. Genomic findings have advanced the diagnosis and treatment of many diseases. “Already, doctors can better categorize some cancers by examining the constellation of genomic changes in an individual tumor rather than simply establishing the anatomical origins of that tumor; this refined categorization will often lead to more appropriate treatment” (Nov. 2011: Human Genome Project Produces Many Benefits, n.d.). Medical treatments for common medical issues are also benefiting from the HGP. Some medications can be effected by gene variants that compromise the effectiveness of the medication while other gene variants can heighten the effectiveness. “Testing the patient’s genome first can make the treatment more effective by minimizing the risk of prescribing the wrong dose” (Nov. 2011: Human Genome Project Produces Many Benefits, n.d.). What the HGP did when it achieved its goal of identifying all the genes in human DNA, and determining...

...Multicultural psychology is developing as a necessary training for individuals working in human services, especially in psychology. Race, sex, color, or even religions are often an important part of training in multicultural psychology, but with new issues these basic factors need expansion. Obesity is a common factor many Americans struggle with as more than two-thirds of the population deals with, but training on is severely lacking for human services workers (Pascal & Kerpius, 2012). Mapping the human gene will also bring new information but also fear and unknown problems. Obesity Psychologists must work to maintain awareness on bias and perception to ensure appropriate assistance is provided to every client. The issues of race, color, or even age many view as elements an individual has no control over but obesity appears to be a choice. The views of many are that an individual who is obese or overweight is that way by choice or laziness resulting in a negative bias that can prevent therapeutic treatment (Pascal & Kerpius, 2012). Viewing an individual as obese also lends to beliefs of he or she is unintelligent, less productive, but caring (Pascal & Kerpius, 2012). The views of others can have long-term effects on an individual and create low self esteem as well as issues such as binge eating and depression. In a situation in which a therapist maintains these views it can exacerbate these issues taking a therapeutic relationship and creating a harmful one (Pascal...

...The HGP progressed and disclosed protein coding regions, non-coding regions in genetic material, conserved transcription mechanisms, epigenomic mapping, and much more (Lander, 2001). In the context of medical disease, the HGP identified principles of genetic mapping, and disease pathways to better understand the genetics of disease. Prior to the findings of the HGP, there were less than 100 genes linked to disease and years later, more than 2,000 genes linked to disease were identified (Lander, 2011). This knowledge has been the basis of many medical breakthroughs but has also provided the means to develop pathogenic genes that would exploit human genetic faults that make humans more susceptible to disease. More than 500 virus, 200 natural plasmids, and 30 bacteria genomes have been sequenced and provide the genetic layout of how to manipulate their genome to make them more pathogenic (Lander, 2001). Different from transferring pathogenic genes from one species to another, synthetic genes could be made to produce proteins that have pathogenic properties that currently do not exist making treatment and prevention grim. After influenza vaccines are developed and distributed, someone could potentially modify the predicted viral strain and make...

...baby refers to the genetic modification of the child in its early fetal life. The world of genetic modification has long moved on from the days of Dolly the Sheep. How is a designer baby created? * An embryo is created by in-vitro fertilization (IVF). * A single cell is removed from that embryo within the first 5 days of its creation. * The cell is genetically tested. * The parents decide whether to discard the embryo or implant it in the mother's womb. Human Genome Project The Human Genome Project (HGP) was the international, collaborative research program whose goal was the complete mapping and understanding of all the genes of human beings. All our genes together are known as our "genome." The Human Genome Project started in the 1980s as an organized effort to provide the information researchers need to understand the genetic basis of all disease. GINA is the first major federal law to come out of the Ethical, Legal and Social Implications portion of the Human Genome Project. This law made sure that people were treated fairly when it came to getting a job and stuff like that even if they had a disorder or disease Literature review Mark Hughes, a pioneer of the PGD process and director of Genesis Genetics Institute says, “It’s technically feasible and it can be done,” adding that “no legitimate lab...

...Heredity is defined as the transmission of genetic characters from parents to offspring Professor Donald C Biology 122 04/22/2013 Heredity Is Defined As The Transmission Of Genetic Characters From Parents To Offspring Introduction Anatomy refers to the science dealing with the description and identification of the structure of organs, tissues and organisms. It studies the body parts structures and how they relate with each other; it enables us to understand the relationship between the bones, muscles, ligaments and tendons. On the other hand, Physiology is the science which studies the functions of tissues, cell, organisms and organs. Physiology combines both physics and chemistry in its explanations. Physiology therefore, refers to the study of how the body functions. The reproductive system of male organs is specialized for: the production, transportation and maintain the sperm (these are the male reproductive cells) and also included are the semen, which is the protective fluid. Another function for the male reproductive organs is to discharge the male reproductive cells into the female reproductive tract. They also secrete and produce male sex hormones. The female anatomical structure is more complicated than the males’. There are many distinct anatomical structures comprising both internal and external tracts of the female genitalia; corpus spongiosum and labia minora (vestibular), urethra, G-spot, Halban’s fascia and peri-urethral glans, cervix...

...Life on Earth first started about 3.8 billion years ago and life has come a long way since then. Human Beings have always had a huge interest in ourselves, the biggest question of all is how do we work and where do our gean come from? It all started with Gregor Mendel, who is know as the father of genetics. In 19th century Gregor started a pea plant garden for crossing pea plant varieties to prove that the heights, colors of the plant and peas, pod shapes, seed shapes, and flower positions was based on traits from the mother and father pea plates passed down to their offspring. Between the years of 1856 and 1863, he prove his hypothesis. In 1953 James Watson and Francis Crick discover the double helix structure of DNA. In James Watson and Francis...

...director of the lab. He worked there for thirty-five years, transferring from classical biology to molecular biology, to work on finding cures for genetic diseases. Watson once said that he would now be dedicating his life to exploring molecular biology to find a cure to cancer, neurological diseases, and to end human suffering from genetic disorders. After countless years of research and tests, Watson headed the Human Genome Project, a research team dedicated to sequencing the human genome, and to use that to find cures for genetic diseases. On October 25th, 2007, Watson resigned from his position at Cold Spring Harbor Laboratory. He claimed he was too old to continue his job, however it is believed that the real reason for retirement was the racial remarks he said of African people, and the conflicts that arose within his lab. He now loves walking and bird watching, occasionally giving talks about his life and his contributions to science today. Those contributions include new advances in genetic studies, mapping of the human genome, and many other advances in genetic cures. Today, many scientists use his work to discover new ways of learning about the human genome and to find cures for genetic disorders. ...

...In 1953, two scientists James Watson and Francis Click published the description of the double helix structure of the DNA. Little did they know that voyage from the double helix to The Human Genome Project (HGP) would become a reality. Fifty years later in 2003, National Institute Health accomplished mapping of 32,000 genes of the human genome. Gene mapping was a significant research that enabled researchers to focus on gene specific diseases and birth defects. More than 1000 research projects started inward voyage discovery of human kind rather outward exploration of the planets. Clinical research involving human beings have greater potential for risk of misusing the technology. Potential for misusing the genetic research and fear of unknown long term effects on the successive generations have sparked bioethics debates. Like abortion, gene mapping is a very controversial subject and both sides have strong views. For example, should a woman abort the pregnancy based on the abnormal genetic screening results? Genetic technology provides an enormous power within our grips and with this enormous power comes following the ethical standards. Ethical standards should be followed involving human subjects. Genetic screening standards should align with four ethical principles of: • Respect for the human autonomy, dignity, and obtaining informed consent • Genetic screening should cause the minimal amount of harm to the subject • Provides maximum benefit to the subject • Genetic screening...

...Hi Krisherm, Thank you for well-explained post on genetic counseling. With the question you have raised for us on genetic counseling, it has given me the chance to research and learn about genetic education and the implications to our physical therapy profession. Krisherm, I apologized in advance for my different take on genetic counseling, which discusses not so much on prenatal screens but more so on human genetics. I realized that I was researching more on generalized screening per se. To answer your question: [What are your thoughts on genetic counseling? Should we impart our professional beliefs and personal values when our patients ask us regarding this subject?] The advances of human genetics can pose affirmation of therapeutic benefits in the fields of medicine. Goldberg (2005) contended The Human Genome Project [HGP] flourished in 1995 was initiated with goals of sequencing and mapping of human genome by year 2005. It proceeded to let patients (suffering from genetic condition like cancer), set hope of being able to identify the genes that predisposes to tumor formation. One such example is the BRCA1 influencing susceptibility to breast and ovarian...

...aims to understand the structure of the genome, including the mapping genes and sequencing the DNA. Genomics examines the molecular mechanisms and the interplay of genetic and environmental factors in disease. It is used to determine the entire DNA sequence of an organisms and a fine scale genetic mapping. The field also includes study of intra genomic phenomena such as Hetrosis, Epistasis, Pleiotropy and other interactions between loci and alleles within the genome. 2.History: The term genome was introduced by H. Winkler in 1920 to denote the complete set of chromosomal and extra chromosomal genes present in an organism, including a virus. This term is used in the same sense even today. The term genomics was coined by T.H. Roderick sometime in 1987 mean mapping and sequencing to analyze the structure and organization of genomes. But today genomics includes sequencing of genomes, determination of the complete set of proteins encoded by an organism, and the functioning of genes and metabolic pathways in an organism. Thus genomics not only deals with the determination of the genetic information present in an organism, but also with the understanding the mechanism by which this information is used by the organism. A major branch of genomics is still concerned with sequencing the genomes of various organisms, but the knowledge of full genomes has created the possibility for the field...
