genotype for PV92, a human-specific Alu insertion on chromosome 16. PV92 only has two alleles: the presence (+) of the Alu insertion, or the absence (-). This means that you will have one of three PV92 genotypes (++,+-,or --). 1. Evolution: Genetic Evidence – Transposons. During or after you watch the video, answer the following questions: What is a transposon? What is a SINE? short interspers transposable elements that are usless to the gemome but can be used to be compares to other sequences

Cystic Fibrosis (CF) is an additional genetic disorder that can cause several implications to a patient. Cystic Fibrosis is the most prominent single- gene genetic disorder. An individual inherits the disease through a combination of both parents having the CF gene in their genetic make up. Cystic Fibrosis is a disease that mainly affects the digestive system and lungs of a carrier. The defective gene causes the body to produce “a thick, sticky buildup of mucus in the lungs, pancreas and other organs

Rationale Does mutations always lead to diseases? Mutation can either lead to diseases or be beneficial to an organism. The ability of DNA to mutate enables life to overcome changes in the environment. Mutation are a natural occurrence in all organism. It could occur spontaneously through errors during DNA replication. It could also occur when the organism is exposed to mutagens such as chemicals or radiation resulting in insertion, deletion or replacing DNA base. Not all mutations will affect

function of the Alu sequences. So far, the Alu gene characteristics are only useful when present within introns of specific genes. The combination of the Alu and introns can help determine relatedness among individuals and become a measurement of genetic variation. During this experiment there will not be any reference to disease or relatedness among

As we advance as a society and as a race, the question of ethics arises. From the time we were cave dwellers to bustling city builders we have been ever changing. Now that we have advanced to the point of remarkable technology and gene manipulation, it’s time we finally discuss how far we should go in actually using and manipulating ourselves with what we have learned. It’s truly inspiring how far we’ve come and the things that we have discovered, but we must be extremely careful not to cross the

progress towards that ideal. It’s been shown time and time again that ideas spark inspiration, theory, experiments, and eventually that gradual scientific process inevitably leads to change. As a Biology major with a specialization in developmental genetics, I am especially interested in how we can learn from DNA, also referred to as the “blueprint of life”, to make ourselves and our world exceptional. The first method of sequencing DNA was developed in the 1970’s by Fred Sanger; this came

Genetic testing is an important scientific-medical process. It is actually used very commonly and for many different purposes. Running genetic tests have a variety of use because doctors and scientist can identify a genetic disorders, diseases , study DNA, genes, and chromosomes, and it can even be used for forensic testing. Although genetic testing is a great medical tool, genetic testing does not prevent a disorder or disease. Genetic testing informs when there is a disorder or disease, it’s most

Pathophysiology of Cystic Fibrosis Cystic Fibrosis is the disorder associated with mutations in the CF trans membrane conductance regulator genes found on chromosome 7- and has been described as the most common lethal genetic disorder in Caucasians. This autosomal recessive disorder wreaks havoc on various epithelial lined organs but its manifestation in the lungs of the patient have been found to be the dominant source of morbidity and mortality. The CFTR gene functions as a regulator for salt

Introduction Aperts syndrome is a developmental disorder of genetic origin. It is caused by a mutation of chromosome ten and is common in older dads. The disorder is due to many different reasons and is treated accordingly depending on the various symptoms. This syndrome is characterized by iconic signs and symptoms. Aperts also affects many people in many ways such as physically and intellectually. Aperts syndrome is preventable but only by abstinence. Pathophysiology, Incidence, and Diagnosis

• Curly x Wildtype “+” the wildtype (normal gene) and “Cy” the curly (mutant gene) 1. Given that Curly is a dominant trait, what percentage of these offspring should be expected to express the mutation (have curly wings)? B. 50% of the offspring are expected to have the curly wing mutation. 2. What percentage will have the normal (wildtype) wings? C. 50% of the offspring will have normal wildtype wings. 3. Organisms are called carriers of a gene if they do not express it themselves but they
