    this process carries on until a stop codon is reached (OCR, 2008). The process whereby AA are bought and a peptide bond forms between them is called protein synthesis. The final protein that is made during protein synthesis causes the phenotype. The term phenotype refers to the observable characteristics of an individual e.g. eye colour, hair colour or shape of…

    characterized by variable and reversible airflow obstruction. The symptoms of asthma include shortness of breath, cough, chest tightness and wheezing. Genetic factors are thought to play an important role in the development of the disease, however the phenotype expression is profoundly affected by environmental factors1. Asthma affects 334 million people all over the world and is the most common chronic disease among children2. In the UK alone, 5.4 million people suffer from asthma of which 4.3…

    identify your partners and as well as your own phenotype and genotype. We did that by deeply observing our bodies and then determining whether we have the following traits. PTC, Darwin’s ear point, ear lobe attachment, hitchhiker’s thumb, widow’s peak, second finger shorter than fourth, bent little finger, mid digital hair, red green color blindness, and tongue rolling. We then made punnet squares by showing all the possible genotype and phenotype outcomes. Apart from…

    Purpose: The purpose of this simulation is to demonstrate how alleles work and practice the skill of figuring out what genotype is dominate based off of the phenotype of the offsprings. Background info: Fruit flies or Drosophila melanogaster work best in experiments because Drosophila melanogaster has 60% of genes that are mutated, amplified, or deleted in human diseases. Drosophila melanogaster also has a short lifespan which makes them best for quick experiments. They also mate and develop…

    fully functioning and expressing proteins hence they do not share the same phenotype. This difference in phenotype is biological in nature and it may be due to the fact of the epigenetics in the womb effecting each twin’s final phenotype. Then of course, other environmental aspects could affect the phenotype of the twins. For instance, one twin could catch a virus, which leads to cancer, and further changes there phenotype from their identical twin. These epigenetic differences become acquired…

    CYP2D6 is a Phase I oxidative metabolism enzyme that is clinically important because about 20-25% of clinically used drug are metabolized by the CYP2D6 enzyme. CYP2D6 substrates are typically lipophilic and include drugs such as antidepressants, antipsychotics, antiarrhythmic, antiemetic, and opioids. The exact clinical effect of the polymorphism is dependent on the drug and the variant alleles expressed because individual allele variants can lead to a range of metabolic ability from ultrarapid…

    This week’s readings have to do with race and genetics in correlation with biomedicine. In Troy Duster’s Race and Reification in Science, he talked about the ability to use genomic knowledge and apply it to the pharmaceutical field. Anne Fausto-Sterling’s The Bare Bones of Race talked about, the racial difference in bone density and uses and definitions of race in medicine. Joan H. Fujimura, Troy Duster, and Ramya Rajagopalan’s collective piece, Special Issue on race, Genomics, and Biomedicine,…

    determine whether the drosophila Melanogaster fly cross will follow Mendel’s law of Independent assortment in a 9:3:3:1 phenotypic ratio a dihybrid cross was performed of cinnabar brown flies with wild type flies. It was observed that the mutant phenotypes became visible in the second filial generation, thus following the law of independent assortment in the first filial generation. It was also concluded that in the first filial generation the dominant genotypes masked the phenotypic effects of…

    signaling pathway. The research should identify the effects in the interaction of the product of Hairless with other gene products, produced by the blockage. The Hairless gene demonstrate that the phenotype of an organism does not provide information about the function of a gene. The expressivity of a specific phenotype is the result of gene-to-gene interactions, gene-to-protein interactions, and many other molecular…

    The genes in our DNA are what decided what our phenotypes would be, or how we were going to look like. But I don’t think it is accurate to say DNA is responsible for our phenotypes, I believe everything that affects our DNA is what is responsible for our phenotype. Our DNA would be different if I had different parents or if environmental factors took place. Yes, once the DNA is set into place it cannot change (obviously). But before that moment so much can happen that the possibilities are…
