Gene

hardly needed for viewing), Dichaete is one of the most commonly used mutations in fly labs. One of the gene 's most important functions is that it encodes a SOX-domain protein required for embryonic segmentation. The gene plays a key role in the early development of D. melanogaster, also supporting the transcriptional regulation of necessary developmental genes rather than regulating any one of the genes (Russell, 1996). Another name for Dichaete is fish-hook (symbol: fish). An experiment was…

Name: Enrique Vazquez PS ID #: 1259993 BIOL 3311 Fall 2014 Date: October 2, 2014 Gene: Bar TA Instructor Name: Fahmi Mesmar Lab Section: 16258 Writing Assignment 3: Eye morphology of Drosophila melanogaster; Bar mutation effects on ommatidial development of the compound eye. Introduction: Drosophila melanogaster have been used for centuries as model organisms due to their relatively small size as well as their inexpensive and simple diet. Fruit flies also have to ability to reproduce in…

future generations are heading. During the first few minutes of the video Enriquez introduces the expansion of the universe. He explains the formation of the galaxy, Earth, and life. He then introduces the process of genome mapping and how different genes are being discovered that might show humans are different. He explains how it is now possible to recreate organisms and human organs from a single skin cell and a few chemicals. Finally, he talks about the brain and how there has been an…

transformation. The organism used was E. Coli because singular cell organisms can have a new gene more easily inserted than multi-cellular organisms. The gene which was inserted is pGLO that carried the gene encoding GFP and a gene for resistance to the antibiotic ampicillin. The GFP gene, in the pGLO, is a gene that that produces a fluorescent protein, which glows when it is placed under an ultraviolet light. For the gene to be turned on, the sugar arabinose is added. In order to determine how…

A mutation is a change in letters that make up our genes. It is a copying error that happens when our cells divide. Mutations are neither good or bad. The change of colors in the mice comes down to four chemical letters. The mutation has spread very quickly in the mice due to how many offspring’s the mice…

The video “Public Genome” demonstrate an interesting perspective about how our genes play a vital role in our predisposition for certain diseases such as Alzheimer or cancer. Fragments of the six billion letters in our DNA are what makes up a gene found on our chromosome. In humans, these 20,000 plus genes transcribes to form a mature mRNA which then gets translated in the ribosome to produce a particular protein like collagen for our skin or hemoglobin in our red blood cells. Although knowing…

codons. Studies by Jan C. Biro found that the number of synonymous codons shows a significant correlation with the frequency of their respective amino acids. Furthermore, the redundancy of these codons may be evolutionary favorable. For example, genes have an increased resistance to mutation given the multiple possible codons for each amino acid – the third nucleotide in the codon can often be interchanged without causing any significant effect on the primary sequence of the protein (wobble…

multiple nuclear gene encoding small subunits of Rubisco is called rbcS. rbcS exists only in Rubisco form 1 so that it is not absolutely essential for carboxylate activity, however it is apparent that rbcS influence catalyze indirectly as following possibilities (Spreitzer et al., 2002). rbcS could have a role to determine the carboxylation efficiency…

Assignment 3.05 DNA DNA, deoxyribonucleic acid, is the stuff in humans and almost all other organisms. About every cell in you and everyone else's body has the same DNA. DNA is usually located in the cell nucleus (nuclear DNA),however small amounts of DNA can be found in the mitochondria (mitochondrial DNA or mtDNA). The DNA has information stored as a code created by four chemical bases: adenine (A), cytosine (C), guanine (G), and thymine (T). Each base is connected to a sugar molecule and…

Alopecia Areata Alopecia Areata is a common autoimmune disease that affects the hair growth. Although this disease is only passed through genetics, but it differs from a single-gene disease. Both parents have to contribute a certain number of specific genes in order for their child to get this disease. Because of this it is rarely passed from parent to child. Now for identical twins it is much different. There is a very low chance that both twins will get it. There is only a 55% for each…
