gene mutation is presented on and the exact location on that chromosome. In order to do so many cycles of crosses were completed using linkage analysis on Drosophila melanogaster‚ a type of fruit fly used in this experiment to identify our unknown gene mutation‚ unknown. Using virgin bar females crossed with Curly/Plum; Dichaete/Stubble male fruit flies represented our Discriminant Cross one (DC1). The DC1 piloted that the unknown mutation is sex linked dominant. Knowing the mutation is sex

Allowed word count: 1500 Actual word count: 1498 Introduction Leber’s hereditary optic neuropathy (LHON) is an optical nerve dysfunction caused by mtDNA mutation that generally causes bilateral loss of sight in young adult men between the ages of 18 and 35 due to degradation of the optical nerve and retinal ganglion cells (RGCs). Although LHON generally affects young adults it can affect children as young

carcinogenesis with these risk factors dependent and independent manner. Ras is one of the most frequently genetically deregulated oncogene in oral cancer. In this review‚ we analyze the past 22 years of literature on genetic alterations such as mutations and amplifications of the isoforms of the ras oncogene in oral cancer. Further‚ we addressed the isoformspecific role of the ras in oral carcinogenesis. We also discussed how targeting the Akt and MEK‚ downstream effectors of the PI3K/Akt and MAPK

The first is mutation. Mutation is a change in the genetic code. Mutations can spontaneous‚ for reasons unknown. They are only evolutionarily important if their in a sex cell. This can be caused by radiation or toxic chemicals. The second is Natural selection. Natural selection is the biological characteristics that enhance survival‚ they will increase in frequency from generation to generation. Fitness has a lot to do with Natural selection. Fitness is the ability for an offspring to survive and

Ehlers Danlos Syndrome Ehlers Danlos Syndrome (EDS) is a disorder that weakens the connective tissues within the body. Connective tissues support the bones‚ skin‚ blood vessels and in turn internal organs are effected. This syndrome can range in severity from mild to life threatening and about 1 in 5‚000 people with 10 different types of this genetic disorder are affected worldwide. My interest was struck in this syndrome when I was caring for a patient who was a former nurse who is now severely

detrimental and can cause various significant diseases. C282Y and H63D are mutations found on the HFE gene and are the major cause of inherited iron overload (hereditary hemochromatosis). As a result‚ iron regulation is disrupted and too much iron is absorbed from a strong transferrin signal as if the body were iron deficient. Consequently‚ this leads to iron overload‚ or hemochromatosis. The three most common HFE mutation genotypes in hereditary hemochromatosis are homozygous H63D‚ homozygous C282Y

(1990)‚ A rare disease that causes visual imparity‚ retinitis pigmentosa‚ is due to SNP mutations in the rhodopsin receptor. RP varies from the age of onset to its severity of the disease itself. With most cases having a gradual loss of the RPE cells and degradation of the cones and rods photoreceptor cells‚ nyctalopia and tunnel vision are primary indicators of the disease being present in humans. The rhodopsin mutation consists of a G-T nucleotide substitution at the 152nd position in the amino acid
