Researchers have found that there are 6 genotypes of the hepatitis C virus and they all may respond differently to treatment. Careful screening of the patient and identification of the genotype is necessary before starting the treatment in order to determine the most effective treatment for the patient. Approximately 15% to 25% of people who are infected with hepatitis

Hepatitis C 12/02009 By: Shuntrice Hannah Abstract Hepatitis C is an infection of the liver caused by the hepatitis C virus (HCV). It is difficult for the human immune system to eliminate the virus from the body‚ and infection with HCV usually becomes chronic. Over decades‚ chronic infection with HCV damages the liver and can cause liver failure in some people. The hepatitis C virus is transmitted mainly by contact with blood or blood products. The Sharing of contaminated needles

Chapter 9: Patterns of Inheritance What pattern will inheritance follow? Why is it important? Always follow patterns? Rule of Probability In tossing a coin the odds of either a head or tail is always 50%. The outcome is unaffected by the previous attempt. If 2 coins are tossed‚ each will be dependent of the other HH‚ HT‚ TH‚ TT (Probability is 25% or ¼) The rules also hold true for genetics due to the law of independent assortment. Each alternative type of outcome in a gene acts independently

Key Terms Active transport: membrane proteins use cellular energy (usually ATP) to move molecules or ions across a plasma membrane against their concentration gradient. Allele: different forms of a gene • genotype – the combination of alleles in an organism. Aquaporin: a specialised channel protein in the plasma membrane of a cell‚ which is selectively permeable to water. Attachment protein: a protein in the plasma membrane of a cell that attaches either to the cytoskeleton inside the cell‚

Discussion The goal of the experiment was to determine what gene or genes are responsible for the white eye phenotype of two strains of Drosophila melanogaster. According the literature‚ the w+ gene is located on the X chromosome at 1.5 genetic map units (1). In addition‚ the st+ and bw+ genes are autosomal and assort independently‚ meaning they are two different genes located on two different chromosomes. It is stated that the bw+ gene is located on the 2R chromosome at 104.5 map units (2)

Chapter 10 Foundations of Genetics Lecture Notes 1 Foundations of Genetics Mendel and the Garden pea The father of modern Genetics is Gregor Mendel. Gregor Mendel (1822-1884) was an Austrian monk who lived in a monastery where the experiments with the garden pea were performed. Mendel’s work with the garden pea was the fundamental study which unveiled the laws that govern genetics and heredity. Mendel was the first to use the scientific method in a very systematic and analysed his results

. Introduction The common bean (Phaseolus vulgaris L.) is the most important food legume crop grown worldwide (Wortmann and Allen‚ 1994; Wortmann et al.‚ 1998; Buruchara‚ 2006). Beans are considered by many to be the perfect food as they are nutrient dense with high contents of protein‚ micronutrients especially iron and zinc‚ vitamins‚ and dietary fibre (Wortmann and Allen‚ 1994; Bennink‚ 2005; Widers‚ 2006). The crop is currently the second most important source of human dietary protein (Buruchara

Genetic influences on aggression Genes do not directly cause aggression but influence elements of our biology that contribute to it. This can be demonstrated through the following methods; 1.Animal Breeding Studies In animal breeding studies‚ animals are selectively bred for certain traits. If it is possible to breed for aggression‚ this would suggest that genes contribute to aggressiveness. Lagerspetz (1979) bred 25 generations of mice. In each generation‚ she chose the least aggressive individuals
