...Gene Therapy SCI115 Introduction to Biology Professor Cassie Prisco November 28, 2014 Gene therapy is a rapidly growing field of medicine in which genes are introduced into the body to treat diseases. It is the name applied to the treatment of inherited diseases by corrective genetic engineering of the dysfunctional genes. It is part of a broader field called genetic medicine, which involves the screening, diagnosis, prevention and treatment of hereditary conditions in humans. The results of genetic screening can pinpoint a potential problem to which gene therapy can sometimes offer a solution. Genes represent the genetic material that organisms pass on from generation to generation. Therefore, genes are responsible for controlling hereditary traits and provide the basic biological code or blueprint for living organisms. Genes produce protein such as hair and skin as well as proteins that are important for the proper functioning of organs. Mutated or defective genes often cause disease. The purpose of gene therapy is to replace a defective gene with a normal copy of the same gene in attempt to restore function. Initially conceived as an approach for treating inherited diseases, like cystic fibrosis and Huntington's disease, the scope of potential gene therapies has grown to include treatments for cancers, arthritis, and infectious diseases. Although gene therapy testing in humans has rapidly advanced, in general, the field of gene therapy has proven to be problematic...

...of bioinformatics 6 Conclusion 9 References 10 Summary Bioinformatics is a field in biotechnology that involves the application of technology involving computers to manage and analyze biological data. In this, computers are used in gathering, storing, analysis and the merging of biological data. Bioinformatics is not a research area by itself but lies between biological sciences and computational sciences. The main goal of bioinformatics is to review the value of biological information that is hidden in the large amount of data come up a clear picture of the basic biology of organisms. There are several fields that have been revolutionized by the technology used in bioinformatics (Ouzounis & Christos, 2012). These fields include human health, the environment, agriculture, energy and biotechnology. This science of bioinformatics is also called computational biology and has found a lot of use in increasing the quality of life. Bioinformatics developed due to the great need to internalize the DNA which is the code of life. Growth in the field of bioinformatics has been facilitated by development of many DNA sequencing projects. The basic biology of life is controlled by the basic molecule of life called DNA. The DNA acts as the blue print for genes which code for proteins. The proteins coded for by these genes determine the biological composition of all the living organisms. The variation and errors that occur in the replication, transcription and translation...

...Assignment 2: Gene Therapy Brandi Williams Professor Mintesinot Jiru Introduction to Biology SCI 115 August 31, 2014 Gene Therapy Technology What is gene therapy? According to the "Genetics Home Reference", gene therapy is an experimental technique that uses genes to treat or prevent disease. Gene therapy has many factors that allows them to work or sometimes not. Below I will explain gene therapy's importance and how it works. Gene therapy is a treatment that involves altering the genes inside your body's cells to stop disease. (MayoClinic Staff) Also, gene therapy replaces a faulty gene or adds a new gene in an attempt to cure disease or improve the the body's ability to fight disease. Disease can be caused by the genes not working properly, but there's a wide range of disease including, cancer, cysyic fibrosis, heart disease, diabetes, hemophilia and AIDS, that gene therapy holds promise for treating. Also, researchers are still standing how and when to use gene therapy. (MayoClinic Staff) Social and ethical implications of gene therapy is complex and still has underlying concerns that need to be evaluated before being out on the market. Only through clinical trials gene therapy had been tested and successful, but because scientists and doctors not knowing the effectiveness of gene therapy; there are still precautions. For this reason, even though it may have been successful and beneficial for others, some mau not be as fortunate and that will cause another set of problems...

...Gene Technology Nelly Solorzano Strayer University SCI115008VA016-1158-001 Intro to Biology Kerry Lee November 29, 2015 Gene Technology Biological basis - Genetic engineering is a laboratory process by which an individual genome is purposely modified. With genetic engineering a gene from one species can be transferred to another and produce an organism that is transgenic or a gene can be altered and reinserted into an individual of the same species. Either way resulting in genetically modified organism also known as GMO. One GMO being used now is genetically modified or engineered animals which are animals in which modern technology and molecular biology are used to alter their existing characteristics or traits. Genetically modified animals are used for various purposes the biggest one now is bio pharma meaning they are intended to produce substances that can be used for human or animal pharmaceuticals. There is also a development of genetically modified animals for the use of scarce cells, tissue, or organs for transplants into humans known as xenotransplantation such as organs from pigs who are a potential source of organs for transplant. The benefits genetically modified animals can produce depend entirely on the traits that are introduced, for example some animals can be made to grow faster and therefore requiring less food to sustain them other animals have improved fat composition providing a more healthful nutrient profile. As of now no genetic modified...

...Gene Therapy: Genetically Modified Crop Plants Coward Introduction to Biology - SCI 115 Professor Johnson March 4, 2014 Genetically modified organisms have become a standard rather than an exception in America. Since their introduction in the 1990’s, genetically modified (GM) products have conquered agriculture in the United States and hold a large share of the food on American’s plates. (Dupont) Everyone has been exposed to it whether they know it or not. According to the US Department of agriculture by 2012, 88 percent of corn and 94 percent of soy grown in the United States were genetically modified. The purpose of this essay is to explain what genetically modified crop plants are, to discuss the social and ethical implications and to provide my personal view point. Genetically modified organisms (GMOs) are defined as organisms whose genome has been modified as genetic engineering. Transferring a gene from one species to another to provide an organism that is transgenic or a gene that may be altered and reinserted into an individual of the same species are the results of a genetically modified organism. Genes can be introduced into plant cells by way of electric or chemical shocks, by blasting them. The most common GMOs are bacteria and yeast, which have been modified to produce medically important proteins which has benefitted people with diabetes. (Starr, Evers, & Starr, 2013) GMOs or GM is used to refer to...

...Depending on the tools and applications, it often overlaps with the (related) fields of bioengineering and biomedical engineering. For thousands of years, humankind has used biotechnology in agriculture, food production and medicine.[2] The term itself is largely believed to have been coined in 1919 by Hungarian engineer Karl Ereky. In the late 20th and early 21st century, biotechnology has expanded to include new and diverse sciences such as genomics, recombinant gene technologies, applied immunology, and development of pharmaceutical therapies and diagnostic tests.[3] Definitions of biotechnology The concept of 'biotech' or 'biotechnology' encompasses a wide range of procedures (and history) for modifying living organisms according to human purposes — going back to domestication of animals, cultivation of plants, and "improvements" to these through breeding programs that employ artificial selection and hybridization. Modern usage also includes genetic engineering as well as cell and tissue culture technologies. Biotechnology is defined by the American Chemical Society as the application of biological organisms, systems, or processes by various industries to learning about the science of life and the improvement of the value of materials and organisms such as pharmaceuticals, crops, and livestock.[4] In other words, biotechnology can be defined as the mere application of technical advances in life science to develop commercial products. Biotechnology also writes on the pure...

...Scientists identify the genes behind gray hair, curly hair, beard thickness, and the humble monobrow. Some genes decide the color of your hair, while other, considerably less friendly genes influence whether or not you go bald. Now, a University College London study has identified the DNA behind gray hair, curly hair, beard thickness, and even the humble monobrow. The researchers say their results confirm long-held suspicions nursed by unmarried aunts — going gray simply runs in the family. We humans have lost most of our body hair over time, yet the abundance of head hair we’ve managed to retain throughout our evolution varies tremendously from individual to individual, and not just among those who regularly drop a Benjamin at the salon. According to the researchers, the appearance of our hair is mostly an inheritance game as evidenced by the obvious differences appearing on different continents. For example, straight hair is virtually absent from sub-Saharan Africa, while variable hair color is mostly found in West Eurasia. “Interestingly, different genes have been associated with straight hair in Europeans and East Asians, suggesting that this trait evolved independently at least twice,” wrote the team of researchers led by Dr. Kaustubh Adhikari Hair Diversity Adhikari, of UCL’s cell and developmental biology department, and his co-authors analyzed 6,357 people with varied ancestry across Latin America to identify new genes associated with hair color, greying...

...DNA Technology BIO/240 May 6, 2013 DNA Technology INTRO – LEE DNA Technology: Cloning, Gene Therapy, and Stem Cell Research DNA technology encompasses a wide variety of applications and because of the duplicating nature of DNA, it is easy to see how humans could benefit from its manipulation. One such technology is cloning. Cloning technology comes in three forms: recombinant DNA cloning, reproductive cloning, and therapeutic cloning. Cloning Recombinant DNA cloning consists of transferring DNA fragments from an organism to a self-replicating element, like a bacterial plasmid. The fragments join with the cloning vector and are reproduced with the host cell. This technology is most commonly known for its use in genetically modified foods. DNA fragments that code for better tasting, higher nutrient qualities are spliced into regular plants to produce super foods (US Dept of Energy Genome Program, 2009). Reproductive cloning takes all the genetic information out of a cell and replaces it with DNA from the desired organism. With luck, this cell will begin to divide until it becomes an embryo and can be implanted into a host mother (US Dept of Energy Genome Program, 2009). Gene Therapy and Stem Cell Research Therapeutic cloning is by far the most controversial. This type of cloning produces human embryos for use in research, and usually for the stem cells that can be harvested from these embryos. Stem cells can be used to clone organs and body parts from the...
