Genetic Factors Of Gene Mutation - 1801 Words

Gene mutation is an official change in the DNA sequence that makes up a gene. Mutations are affected by the change in the DNA sequence. (U.S NLM, Para I) There can be many different types of mutations. Some examples are point mutations, missense mutation, nonsense mutation, frame shift mutation, silent mutation, deletion, insertion, and duplication. These mutations can either occur naturally or actually made to happen. Mutations can have a huge impact that can be beneficial or unhelpful. (Mutations, Para IV) Mutations can occur in humans, animals, or plants. Mutations affect today’s society in many ways. Mutations can be caused by exogenous or endogenous factors, or they may be caused by mistakes in cellular machinery. Chemical or physical agents that induce mutations in DNA are called mutagens and are said to be mutagenic. Exogenous factors are those that are in the environment such as sunlight, radiation, and smoking can cause mutations. Endogenous factors are those errors during DNA replication can lead to genetic changes as can poisonous products of cellular metabolism. Mutations can be advantageous and lead to an evolutionary benefit of a certain genotype. Mutations can also be harmful or deleterious, which means it could cause diseases, development delays, structural abnormalities, or some other effects. (Mutations, II) There are four types of nucleotides. They all have a different nitrogenous bases which are thymine, adenine, guanine, and cytosine. These fourShow MoreRelatedA Research Study On Genetic Testing Essay1390 Words   |  6 PagesThe use of genetic information has drawn repeated attention from insurance companies in recent years. Especially the introduce of genetic testing in the industry, which can help set the level of cost of premiums for different groups of the population as well as assess the risk. Many parties have been involved in the debate on whether genetic information can be allowed to use by insurers when assessing those a pplications, such as government, insurance companies, health service providers. In the UKRead MoreThe Complicated Biology of Breast Cancer977 Words   |  4 Pagescancer, I decided to use my knowledge and research to guide you through the more complicated biological side of breast cancer. Within this letter I hope to better your understanding of cancer, especially breast cancer. Its the causes, pros and cons of genetic testing, and my recommendations for you and your daughters. I will also discuss the controversial decision of actress Angelina Jolie. Cancer is a term used to describe diseases that include abnormal cell division, which means that cells don’t dieRead MoreGenetics Is A Branch Of Biological Science938 Words   |  4 PagesGenetics is a branch of biological science that focuses on the study of genes and inheritance from parent to offspring. Genes are found in chromosomes embedded in a cell’s nucleus and carry the traits that a person will have. We inherit our traits from our parents through sexual reproduction, when two gametes, a sperm from the father and an ovum from the mother, combine and produce a zygote. Gametes form through meiosis, which results in each gamete having 23 chromosomes. This results in the zygoteRead MoreThe Discovery of Dominant and Recessive Genes by Gregor Mendel939 Words   |  4 PagesIntroduction: Genetics is the study of how genes and heredity combine to create traits in living organisms. Gregor Mendel disproved the theory that heredity comes only from parents. He discover ed that there were dominant and recessive genes and his â€Å"Law of Dominance† has been used to selectively breed plants and animals for particular attributes. It has also been successfully adopted to identify the risk of passing down genetic diseases. Francis Galton took Mendel’s discoveries further by studyingRead MoreGene Expression : The Consequences Of Human DNA And Human Genes1345 Words   |  6 Pagesthese chromosomes are sections of DNA called genes. Genes make up the physical traits inherited and expressed from mom and dad. When the DNA found within these genes provides genetic instructions to encode proteins or other molecules, this is called gene expression. Gene expression is the process by which genetic information stored in a gene dictates a cells function. This process is essential as regulatory proteins control the rate of gene expression. Gene expression is influenced by the processesRead MoreBiological Mechanisms Of The Obesity945 Words   |  4 PagesCandidate genes allow researchers to come up with rational hypothesis of role of these genes and their contribution to different conditions, in this case obesity. Therefore, they are potential predisposition factors. Candidate genes are chosen on a basis of knowledge of their function, biochemistry and their expression pattern (what protein they encode for and where is this protein mainly expressed) in obesity. At present, there are about 300 genes that have been hypothesized to contribute (to someRead MoreRejection to the Proposal of Mr. Clotter John Ko Essay1539 Words   |  7 Pages Is generalised Genetic Screening for Factor V Leiden Necessary? =============================================================== Genetic screening has no doubt have been the one of the most controversial issue in the branch of medicine. The new issue has recently triggered the on-going debate: the dilemma of whether the Government should allow the Genetic screening of all 16 year old girls for mutation in specific gene called the Factor V which sometimes leadRead MoreBrca1 And Brca2 : Factors That Affect The Risk Of Breast Cancer1589 Words   |  7 Pagesinvolved in maintain the integrity of the genome (Kinzler et al, 1997). A mutation in the AT, or ATM, gene on chromosome 11 also is associated with breast cancer, and it may be much more common in the general population than BRCA1 or BRCA2 mutations. Seven percent of familial breast cancer may be associated with the AT gene mutation (Radford and Zehnbauer, 1996, cited in McCain, 1997). It is not known whether the AT mutation increases the risk of breast cancer for men. Ataxia teleangiectasia is anRead More72 New Gene Mutation Essay1074 Words   |  5 Pages72 New Genetic Mutations Linked to Hereditary Breast Cancer According to the National Cancer Institute, invasive breast cancer affects approximately 1 in 8 U.S. women, and about 5% to 10% of all breast cancers are hereditary. At present, most people are familiar with BRCA1 and BRCA2 gene mutations, which are inherited gene mutations—or abnormalities in the DNA sequencing—that increase the risk of developing breast cancer. According to statistics from the National Cancer Institute, by age 70Read MoreWhat Is Melanocortin 1 Manogen?1038 Words   |  5 PagesThe MCR1 gene provides instructions for making a protein called melanocortin 1 receptor. This receptor plays a major role when it comes to pigmentation. This receptor is located on cells that produce melanin called melanocytes. (https://ghr.nlm.nih.gov/gene/MC1R). Melanin is a substance that gives skin, hair, and eyes the color. Melanin is also found in the retina part of the eye, and it gives humans normal vision. Common variations (polymorphisms) in the MC1R gene are associated with normal differences
