The two major categories of mutated genes are firstly oncogenes. These are the cancer causing in rapidly spreading cancers. Mutations of oncogenes may result in direct and continuous stimulations of the pathways that control cellular growth and division and the repair of DNA. These mutations are not inherited. Some common examples of oncogenes are HER2 which is a specialised protein. It controls growth in cancer cells such as breast and ovarian cancer. The other common oncogenes include the Ras family of genes which make proteins involved in cell communication pathways, cell growth and cell death. DNA repair genes fix mistakes made when DNA is copied. If an individual has an error in a DNA repair gene and these mistakes are not corrected, they

    Li Faumeni Syndrome

    According to the American Cancer society, tumor suppressor genes are normal genes that slow down cell division, repair DNA, and mark cells for cell death.2 When these genes are mutated, cell growth is no longer regulated, leading to the possibility of developing cancer. Inherited abnormalities of tumor suppressor genes have been found in some family cancer syndromes and cause certain types of cancer to run in families.2 The p53 gene, which codes for the p53 protein that regulates the cell cycle, has been found in more than half of human cancers.2 This gene is frequently inactivated in a variety of cancers, including leukemias, lymphomas, sarcomas, brain tumors, and carcinomas.3 In this lab experiment, a woman named Valerie is suspected of having…

    Lung Cancer Essay

    Carcinogens bring about mutation in the genes that induce development of cancer. About 30 percent of lung adenocarcinomas are brought about by a mutation in the K-ras proto-oncogene. It has also been reported that epigenetic alterations that happen on genes may lead to inactivation of tumor suppressor genes. This, therefore, implies that proliferation of cells will be uncontrollable leading to lung cancer. The epidermal growth factor receptor (which functions to regulate apoptosis, cell proliferation and tumor invasion) undergoes mutation.…

    The Forever Fix: Genetic Analysis

    And consequently, to understand gene expression is to understand why these mutations can have such grave effects on an individual. For DNA to direct cellular processes, it must be transcribed and translated, The AP Biology Curriculum Framework explains. It goes on to say that “the products of transcription and translation play an important role in determining metabolism, i.e. cellular activities and phenotypes.” So if “changes in a nucleotide sequence, if present in a protein-coding region, can change the amino acid sequence of the polypeptide” (AP Biology Curriculum Framework, p. 37), changes to these essential proteins prevents cellular activities from being performed. The field of gene therapy began due to knowing about mutations and their effects on gene expression.…

    P 53 The Guardian Of The Genome Case Study

    P 53 also known as “the guardian of the genome” is a tumor suppressor gene that works regulating the cell cycle and apoptosis. It is a very important gene since the lack of its action can allow the cells to divide an abnormal number of times and if action is not taken by the cell’s checkpoints, this could lead to cancer. The evolution of tumors associated with mutations in the p53 gremlin is not well understood and numerous researches have been completed trying to identify all of its characteristics. As all inherited gene mutations, p53 mutations are present in all somatic cells, but the effect of these mutations can have malignant effect on the cells.…

    Brca1 And Brca2 Genetic Testing, Should Everyone Do It?

    In my study I found out there non BRCA genes related with breast cancer which emphasizes that other genes are as important as BRCA and harmful mutations in those genes can result in having the same problem. In addition, breast cancer can be caused by the other risk factors such as the environment which is if the person is smoking, she/he is obese, or UV radiation from the sun, and drinking alcohol. Another fact that I looked at was the chance of someone with positive mutation to have breast cancer.…

    A Mutation is a change that occurs in an human’s DNA sequence. It happens when the structure of the gene changes. Making a version that may be transferred to future generations when there’s an alteration of a single base unit in the DNA or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Alexandria’s Genesis is a recessive gene that affects the color of the eyes, as well as multiple body parts.…

    Farber Disease Research Paper

    Farber lipogranulomatosis, or simply Farber’s disease, is a lysosomal storage disorder that involves the hydrolysis and use of lipids. A lysosomal storage disorder is a defect in the function of a lysosome, enzymes that hydrolyze large molecules and then move the fragments on to other parts of the cell for other uses. Farber’s disease is a rare, genetic condition that involves a deficiency in the enzyme, ceramidase. Ceramidase is a lysosomal acid that causes cell growth, cellular differentiation, cell adhesion, the movement of cells and the death of cells. The body is unable to produce ceramidase with Farber’s disease, thus causing the buildup of ceramide.…

    How Does Deletion Mutation Affect Dna Facilitation?

    DNA mutations are in other words DNA changes. Any changes in DNA can be from spontaneous mutation, in order to adapt to the continuous changing environment, or induced mutation, which it is caused from dangerous exposures such as to carcinogens or radiation. Moreover, three main steps a DNA chain goes through to build proteins are, DNA to mRNA (messenger deoxyribonucleic acid), and then the end result is protein. Furthermore, DNA changes, in which can occur in a single or multiple nucleotides on a codon, can cause kinks and bends on proteins. Irregular kinks and bends on proteins can cause the protein to become less active, inactive, or enhanced.…

    Mutated Dna Research Paper

    Some problems associated with mutated DNA are that it introduces defective genes. It can result in the loss of genetic information, causing biological systems to become less complex. It can lead to abnormalities of species. The changing of one single base pair known as point mutation can result from chemical damage proceeded by copying error. If there is a mutation in DNA, the nucleotide sequence is changed, thus changing the sequence of the mRNA codon.…

    Pros And Cons Of Human Genetic Variation

    Genetic mutations may or may not have varying effects on health, depending on where they occur and whether they change the function of essential proteins. There may be various reasons to occur a genetic variation. According to the variation occurred in the gene, mutations are categorized. The types of mutations include: 2.3.1 Missense mutation This type of mutation is a change in one DNA base pair that results in the substitution of one amino acid for another in the protein made by a gene [1], a type of nonsynonymous substitution.

    What Are The Four Different Ways Of Detecting Mutant Statistics

    Mutant Statistics are statistics that started out in a correct manner before people misinterpreted and exaggerated them, therefore causing it to be viewed inaccurately. Advocates and the media often mutate statistics and those who hear it will often accept it and repeat it. Many media groups repeat the statistics they have heard to their audiences, therefore having the audience repeat it to people they know, until it is widely heard of and believed. However, mutant statistics are not always evidence of dishonesty. Sometimes the statistics start out bad, and without the proper research they are continuously carried throughout the believing groups.…
