Vanessa Campos 10/15/2015 Anth 300: Essay 1 Professor: Katrina Worley Genetics and Evolutionary Theory There are some people out there that don’t believe in science such as evolution‚ natural selection‚ genetics‚ and so on. You name it. Anyway‚ the theory of evolution for the development of species is a theory. Not all scientists can get the truth because it a little hard work to get the evidence but their theory says it can happen to this or that. There are three way to explain in science‚ what
Premium Evolution DNA Natural selection
The four forces of evolution include mutation‚ gene flow‚ genetic drift‚ and natural selection. Mutation is when there is a change occurs in a gene or chromosome structure which results in a difference in a physical or behavior trait. This trait can be carried into the next generation because the trait is contained in the gene. Gene flow is the process of genes transferring from one population to another. Genes can be transferred to different populations by migration of individuals along with the

p53 protein with its unique C- and N-terminal structures is rigidly modulated by several important biological processes such as phosphorylation‚ acetylation and ubiquitination‚ through which it effectively regulates cell growth and cell death. p53 mutations can lead either to loss or change of p53 binding activity to its downstream targets and may thus induce aberrant cell proliferation‚ with consequent malignant cellular transformation. Based on p53’s critical role in carcinogenesis‚ scientists have

Hutchinson-Gilford Disease (Progeria) Only one in every four million kids is known to be diagnosed with Hutchinson-Gilford Progeria Syndrome‚ or most commonly known as Progeria syndrome or “Aging disease.” Progeria syndrome was first founded in 1886 by Dr. Jonathan Hutchinson and by Dr. Hastings Gilford in 1904. Progeria Syndrome is extremely rare and newborns appear to be normal at birth until the first year when the first signs of symptoms begin to appear. Since first found‚ only 130 cases have

Disease Overview Von Recklinghausen’s disease‚ also called Neurofibromatosis Type I (NF1) is one of the most common types of inherited single gene disorder which effects approximately 1 in a disorder caused by a mutation in the tumor suppressor neurofibromin (NF1) gene located on chromosome 17 q11.2 and is inherited in an autosomal dominant manner. The neurofibromin gene primarily affects the development and growth of neural cell tissues as well as the regulation of melanogenesis so the defect

if your chromosomes are positive for a genetic mutation. Test results can provide a sense of relief from uncertainty about having a mentally or physical ill child because no one wants that for your child. They also help people make informed decisions about managing their health care. For example‚ a negative result for the mutation can eliminate the need for unnecessary checkups and screening tests in some cases. A positive result‚ having the mutation‚ can direct a person toward available prevention

It relies on the observation that the most common cause of cancer is somatic mutations brought about by DNA damage. It was first developed by

people‚ achondroplasia is caused by a mutation in the fibroblast growth factor receptor-3 gene (FGFR3)‚ which is located on chromosome 4‚ causing abnormally short stature (Schoenstadt). Achondroplasia comes from the Greek word meaning “without cartilage formation” as the defect causes the body to be unable to change cartilage into bone‚ causing failure for bones to reach normal adult size (Ellis-Christensen). As stated before‚ achondroplasia is caused by a mutation in the FGFR3 gene which is responsible

Why offspring produced by the same parents are different in appearance Offspring differ somewhat from their parents and from one another. Instructions for development are passed from parents to offspring in thousands of discrete genes‚ each of which is now known to be a segment of a molecule of DNA. This essay will explore some of the reasons behind how and why these differences in appearance arise‚ from the base sequence of DNA through to the observed phenotype. Genes come in different varieties
