Gene

Pre-symptomatic (or predictive) testing, confirmatory testing, and prenatal testing [16]. Prenatal testing, through tests such as chorionic villi sampling (around weeks 10-11) and amniocentesis (at weeks 14-18) can be used to test the fetus for the abnormal gene and inform parents. Pre-symptomatic testing is used for those that are at risk of having HD, based on family history, but have not presented with any signs of the disease. Confirmatory, or diagnostic, testing is used for patients that…

mutation on the LMNA gene (Burtner; Reunert et. al, 2012; Rodriguez et al., 2009). The genetic cause of Progeria is a mutation on the LMNA gene located on Chromosome 1 (Gulli & Mallory, 2002; Reunert et. al, 2012). Specifically differentiating Progeria from other laminopathies is that the mutation is located on exon 11. The LMNA gene encodes for A-type Lamins which are the inner nuclear lamina involved in maintenance of the nuclear shape and structure, DNA replication and gene expression…

identifying the unknown gene. The cross was set up between parents with similar phenotypes. Two results were expected from this crosses, one of the crosses would show the complementation of two mutant alleles and the other cross would show two allelic mutations. If the two mutant allele complement each other all the progeny will be wild type, and thus are likely mutations in two different genes. However, if the progeny displays hot cheeto the two mutations are allelic and in the same gene. We…

antibiotics, it kills off other bacteria and allows antibiotic resistant bacteria to survive and multiply. This causes contamination of animal waste, which then comes into contact with water, soil, or air (Food, Farm, Animals, and Drugs 2014). Horizontal gene transfer is also a big concern for the environment. In recent years, there has been an increase in antibiotic resistant bacteria found. The antibiotics that are given to the animals get in contact with their immediate environment, but…

From the humble beginnings of specific breeding to manually changing DNA, genetic engineering has been controversial to say the least. As genetic engineering continues to grow more ethical issues seem to pop up, especially when dealing with human genetic engineering. There are many different uses for genetic engineering, yet human genetic engineering is to unethical to continue. To fully understand why human genetic engineering shouldn’t be allowed one needs to understand the history of genetic…

present in nearly all living beings. The DNA carries all the genetic information of that specific being. Humans and animal DNA was discovered to be very similar, so scientist questions what they could do with that information. In the article “ Will gene-altered athletes kill sports? Soon animal DNA could make us faster and stronger.no training needed” by Gregory M. Lamb, he wrote about how scientists are mixing human DNA with animal DNA. Even though humans share most DNA with different animals,…

1) A.) The specific DNA changes caused by the delta F508 mutation, include a production of the abnormal cystic fibrosis protein. This mutation can only be inherited if both genes in pair of DNA carry the cystic fibrosis mutation. The specific mutation functions as a chloride channel, that has an abnormal amount of salt and water balance. Normally a chloride channel would help to maintain the right balance salt and water inside a cell, but those mutated with F508 mutation, are imbalanced causing…

6F4Z1003- Genetics, Adaptation and Diversity Practical Report Section 1- Calculations and Pedigrees 1. In DNA extraction the proteins absorb light at 260nm and 280nm, especially the aromatic acids. 2. 250µg to nm, 250 x 1000 = 250,000ng. 3. 200ng/ml = 0.2µg/ml. 150µg/ml = 150,000µg/ml 250,000pg/µl = 250µg/ml 1mg/ml = 1000µg/ml ● 150,00µg/ml - HIGHEST CONCENTRATION OF DNA ● 1000µg/ml ● 250µg/ml ● 0.2µg/ml - LOWEST CONCENTRATION OF DNA 4. Sodium dodecyl sulphate is used as a…

protease inhibitor (serpin), therefore it is also known as serpin E1. Human SERPINE1 gene encodes for PAI-1. PAI-1 inhibits Fibrinolysis through the inhibition of the serine proteases, Tissue plasminogen activator (tPA) and urokinase-type plasminogen activator (uPA), which activate plasminogen. So any increase in PAI-1 decreases fibrinolysis consequently increasing the risk of thrombosis. PAI-1 gene (SERPINE1 gene) is found on chromosome 7q21.3-q22. Its wild type promoter contains five…

Stanley Norman Cohen Stanley Norman Cohen is a scientist known for inventing recombinant DNA technology with Herb Boyer. Cohen was born on February 17, 1935 in a small town of Perth Amboy, New Jersey. During his childhood Cohen frequently helped his father assemble many things such as electrical fans, fluorescent mixtures and many more. Cohen developed an interest in Science from a very small age, but later switched from physics to biology and decided to become a medical doctor. Not only was…
