the population. The virus’s ability to adapt and escape the host’s immune system determines the infection outcome. The high mutation rate can directly affected the virus’ variant resistance toward the HLA alleles and current and future manufactured drugs. Products, CD4+ and CD8+, from HLA allele expression are major determinants for whether an infected person with HCV will clear the virus without medication. Rapid and high change in the virus’s genome gives the virus a selective advantage,…

DNA Modification DNA is the ultimate carrier of an organism’s genetic information. The particular sequence of amino acids determines a being’s height, eye color, susceptible diseases, and precise blueprint. Recent studies have shown that this genetic outline does not have to be permanent. New fields of science such as epigenetics and germ line editing are slowly reshaping the status quo of genetics. Genetic modification is no longer limited to food and animals because scientists are…

Darwinian Snails: Introduction The flat periwinkle is a small snail that lives on seaweeds growing on rocky shores in New England (McRae 2016). The scientific name of the periwinkle snail is Littorina obtusata. They were first introduced to the Atlantic Coast during the 19th century. These snails are known mainly for a morphological trait, the variation of shell thickness within the population. Several studies have been done already to study the evolution of the periwinkle snails shell…

blonde hair blue eyes because the color brown is a dominant gene where the blonde and blue are recessive. Between 1856 and 1863 Mendel cultivated and tested 29,00 pea plants. His studies showed that one in four pea plants had purebred recessive alleles, two out of four were hybrid and one out of four were purebred dominant. At the time his work was criticized, but is now…

Addiction is a complex behavior trait in which multiple genetic loci contribute to the variety in nervous system functions, which is very likely to contribute to methamphetamine (MA) addiction. In this experiment, selective breeding mice self-administered orally, high or low amounts of methamphetamine. The purpose the testing was to identify differences between the MADR lines in terms of genes to influence addiction related processes. The two strains of mice were placed in MA-induced…

Kristin Fitzpatrick BI 456 Immunology Disease Term Paper 11/21/14 Systemic Lupus Erythematosus: Epidemiology, Diagnosis, and Treatment Options I. INTRODUCTION Lupus, Latin for “wolf,” originally referred to the erosive facial lesions that resembled a wound from a wolf’s bite. In the Middle Ages lupus was mainly described as a dermatologic condition. It was not until 1872 that lupus was considered a systemic disease that presented with subcutaneous nodules, arthritis, lymphadenopathy, fever,…

Mcardle’s Disease is a type of glycogen storage disease (also known as glycogenosis or dextrinosis). Glycogen storage disease is the consequence of the deformity of the human body to synthesize glycogen in the liver, or to break glycogen down within the liver and muscles. There are two main types of glycogen storage disease one is genetic GSD (or congenital metabolic disease), which is caused by the defect of genes that do not code the enzymes needed for the synthesis or the conversion of the…

highly unlikely for HGPS to be inherited, because most individuals who possess HGPS do not live to the age of reproduction. Because this condition is known to be heterozygous, this means that the gene that expresses the phenotype for HGPS is a dominant allele. The mutation at codon 608 is on chromosome one, meaning that the mutation is autosomal, and not an X-linked trait. The reason this genetic disorder is not more common for a dominant autosomal trait is largely due to the fact that many and…

Introduction: It is hypothesized that irregular signaling that is regulated by the PDE4B gene plays a role in the expression of symptoms certain neuropsychiatric diseases (i.e. Schizophrenia and Bipolar disorder). Methods: 878 patients with schizophrenia or schizoaffective disorder were analyzed in the study, 644 were Caucasian and 234 were African American(AA). 604 controls subjects were also included, 407 Caucasian and 197 African American. All non-control patients were diagnosed by clinical…

In the case of many elite athletes, there is actually scientific basis for the phrase “natural born talent”, at least to some degree. The increased interest and research opportunity in genetics since the latter twentieth century naturally sparked research within the sport science community in discovering how gene expression correlates to athletic ability. Though countless factors help to determine an athlete’s abilities, genes can play a role in athletic performance. Some of the pertinent…
