is one of the many vital genes that is highly controlled during caloric restriction, which leads to a number of biological variations to extend lifespan. Resveratrol’s activation of the SIRT1 gene affects a number of cellular processes. Resveratrol decreases nuclear factor kappa B (NFκB) activation.The nuclear factor kappa B is located in the cellular cytoplasm and moves to the nucleus upon activation where it stimulates transcription of multiple pro- inflammatory genes such as TNFα, IL-1, and…

I think that designer genes are morally wrong, except when it’s used to cure diseases. There are many reasons designer genes are wrong, and many unforeseen consequences. The majority of scientists think that customizing genes is wrong. You can’t just make “better people” using engineering (theoretically). In World War II, Adolf Hitler tried to make his own “Master Race”. He wanted to give everyone blonde hair and blue eyes by means of genetic engineering (O.I). Scientists in China…

Down Syndrome is caused by a problem arising from the chromosomes given to the baby. A Chromosome is the genes carried by the parents to be passed on to their offspring. The genes from the parents are passed through chromosomes. AS a baby cell develops these chromosomes will pair up to create 23 pairs of chromosomes. Down syndrome is caused by there being three copies of chromosome 21 instead…

made, then you turn off the enzymes that are involved in tryptophan synthesis by binding and causing a change in shape of the enzyme (negative feedback). In addition, repressors are proteins that bind to the operator and prevents expression of the gene. However, the repressor is unable to bind to the operator unless tryptophan is present, in which case the tryptophan is a corepressor which is a small molecule that binds to the repressor. When there is a lot of tryptophan, it will bind to the…

1. One of the first questions that I have for Mariah is if she remembers her mother and stepfather and how did this affect you when you were growing up. Although the case study talks about the father being abusive I would want to know about the mother and their relationship. Then I would ask a follow up question and ask Mariah if she tried looking for her parents and what would she get out of it if she tried to look for her parents. Another question I would have for Mariah is if she could tell…

The Spotted Wing Drosophila fly (SWD) is a quickly spreading across the United States of America. As SWD numbers get larger the number of fruit crops gets smaller. Aijun Zhang, a chemist working with the Agriculture Research Service, Invasive Insect Biocontrol, and the Behavior Laboratory in Beltsville Maryland, has found a solution to the SWD problem, Methyl benzoate. Methyl benzoate is emitted by snapdragons and petunias, to attract bees. SWD, unlike bees, is repelled from Methyl benzoate,…

Our group was assigned fruit flies with the mutated traits of shadow body and stubby wings. These traits were easily identifiable. A shadowed body was gray instead of the wild-type color of light brown, and stubby wings were nearly absent from the organism when they should be prominent. In this experiment, we attempted to determine the mode of inheritance for these two traits. After the parents mated, we viewed their F1 offspring. We noticed this generation didn’t contain either of the…

- Genetic testing is a medical assessment that detects any changes occurring in your genes, proteins or chromosomes. ("What Is Genetic Testing? - Genetics Home Reference." U.S. National Library of Medicine. National Institutes of Health, n.d. Web. 29 Nov. 2016.) - It is used to rule out any genetic condition as well as it can be used to determine a person’s chance of developing a genetic disorder.

James Watson, Francis Crick, Rosalind Franklin and Maurice Wilkins all played a pivotal role in determining the structure of the DNA molecule. The orderly and methodical work at King’s college, London by Rosalind Franklin and Maurice Wilkins provided a more experimental approach, working closely with X-ray diffraction images of DNA, this was juxtaposed to Watson and Cricks who at their Cambridge lab approached research by building physical models, narrowing down possibilities and producing ever…
