CAAT/enhancer binding protein β preferentially binds in the presence of the IL-8 gene +781T allele, which can promote IL-8 gene transcription and regulation.29,36 Thus, we speculate that individuals…

gustatory cells. The gustatory cells are covered with bitter taste receptors. When these receptor are stimulated, a message is sent to the brain that bitterness is detected (Wooding 2006). There are two common alleles in the PTC gene: the tasting allele and the non-tasting allele. Each allele ciphers for a different receptor protein. TAS2R38 is a gene that gives the ability of people to taste PTC (Wooding 2006). A person is homozygote recessive for the TAS2R38 gene if it is not able to taste…

rate of deaths from tuberculosis. Children who receive the homozygous recessive allele gained from Tay-Sachs heterozygous parents, suffer uncontrollable laughter, shaking, muscle control, drooling, sometimes even blindness. This is clearly miserable for the homozygous children, however Diamond exams the idea of heterozygous carriers having benefits from carrying the recessive allele. Analyzing the history of when this allele began to spread, it was observed…

Genetic disorders are inherited conditions caused by DNA mutations. It is common among various people, however, some disorders can be less severe and some can affect lives greatly. One of the common known genetic disorder is ‘Cystic fibrosis’ which is a life-threatening disorder that affects the lungs, pancreas, liver, intestines, sinuses, and sex organs. In one of the article, ‘Gene Therapy for Cystic Fibrosis Shows Some Promise In Study’ by Christian George Acevedo published in the Science…

Law of Dominance is “a recessive alleles will always be masked by dominant alleles”. That means that the dominant trait will always over power the recessive trait. The second law is The Law of Segregation…

is designated as I, and it has three common alleles, which include IA, IB, and i. Different combinations of these three alleles produce four different phenotypes, more commonly referred to as Blood Type A (homozygous IAIA or heterozygous IAi), Blood Type B (homozygous IBIB or heterozygous IBi), Blood Type AB (heterozygous IAIB), and Blood Type O (homozygous ii). The allele IA provides the presence of an A antigen on red blood cells, while the IB allele is responsible for the presence of the B…

pathways, for instance alleles associated with the production of keratin, were augmented in those with Neanderthal ancestry in European and East Asian populations. Sankararaman et al. (2014) propose that Neanderthal genes may have helped anatomically modern humans adapt to non-African environments. The study also found that a number of Neanderthal derived alleles are associated with diseases including type 2 diabetes, lupus and Crohn syndrome. “Deserts” of Neanderthal alleles in certain…

Report 5 Title Detecting possibility of expressing disease condition and presence of cystic fibrosis (CF) associated mutation (△F508 and G551D) in DNA sample using allele specific polymerase chain reaction (ASPCR). Abstract Elevated levels of blood immunoreactive trypsinogen (IRT) may be obtained in patients with cystic fibrosis (CF), when it is detected in primary screen, DNA analysis is performed to look for the 12 most common mutations associated with CF. This study aimed to investigate…

Evolution is defined as the progression of a population which include changes in allele frequencies of a gene pool. The genetic make up or gene pool of the specie going through modification. While the alleles go through the change, so do the traits of the individual. There are mechanisms that are responsible for the change of alleles. The four mechanisms are mutation, gene flow, genetic drift, and natural selection. Every living thing has a different genetic make up or sequence, which can be…
