Mutation

In the paper, “Origin of Species”, author Ray Comfort presents opinions and non-supported assumptions to discredit the contributes of Charles Darwin to science literary. Charles Darwin’s contributions to science by his data, theories, and arguments for evolution by natural selection are exceptionally important in how scientist classify and explain evolution acting in nature. From variation in phenotype to the passing of favorable traits, to succeeding generations, to how life itself became,…

no known cure. Gene Product Classic galactosemia is correlated to mutation of a single gene. That mutation is located on 9p13.3 part of the chromosome. The alteration of the chromosome 9p, in which around 4,000 base pairs are affected by mutation. This usual affect the GALT gene…

Cystic Fibrosis is a disease that is caused by a mutation in the CFTR gene. CFTR stands for cystic fibrosis transmembrane conductance regulator whose mutation commonly leads to the deletion of three nucleotides which code for the amino acid phenylalanine. The mutation, therefore, leads to the loss of this amino acid. The mutant CFTR leads to the disease as the incorrect protein folding is detected in the endoplasmic reticulum which leads the protein to be degraded and thus never reaches the…

identifying the location of the DMD gene mutation, the goal is to restore transcription or to at least restore some type of dystrophin…

reproduction and mutation process. Mutation is one of the main sources of genetic variation. Genes mutate at a certain frequency. Mutations are common in the population. Not all mutations affect genes; most of the mutations accumulated in the non-coding sequences. Basing on its consequences for the organism, mutations can be divided into harmful, useful and neutral. Mutations are the primary changes, which are based evolution and selection. The natural manifestation of mutation is a process that…

with other proteins located underneath the inner membrane of the nucleus. Mutations in the LMNA gene affect lamins dimerization and assembly (Bank et al., 2011; Ben-Harush et al., 2009; Bertrand et al., 2012; Bhattacharjee P, 2013; Gangemi F, 2013; Shumaker et al., 2005; Wiesel et al., 2008; Zwerger et al., 2013). It apparently leads to nuclear stability loss and inability to perform functions in its entirety. The mutations in LMNA lead to at least 10 clinically distinct phenotypes, termed…

and respiration. Mitochondria carry out multiple other functions that are extremely important (such as various forms of signaling) The mitochondria also contains DNA which can have a direct effect on some functions of the human body if there is a mutation. ( Mitochondrion.(2016, October 9)) Word count 63 (not including headings or internal citations) About LHON This disease was first recognized in 1871 by Theodor Leber, a German ophthalmologist. Leber’s hereditary optic neuropathy is an…

Ebola – a pathogen from our worst nightmares was once just the name of a river in northern Zaire, Africa. How did the name of a river give rise to a virus with such a horrifying connotation? The recent Ebola outbreak occurring in West Africa is on high alert across the world. The Ebola virus is lives in animals such as the fruit bat, but has the tendency to make the jump to humans. When this jump does occur, the virus is deadly and kills the majority of those infected. Because the virus is…

Cancer refers to several diseases that the involve uncontrolled growth of mutated cells in the body. Normally, cells grow and divide based on signals and the body’s needs, and new cells replace old or damaged cells. However, cancer is able to develop when cell signaling is interrupted. The old cells stop dying and instead form new abnormal cells, possibly resulting in a tumor. Cancerous cells are malignant, which means they can invade nearby tissue, and can potentially metastasize and spread to…

Among those affected, the severity of the disease can vary. A small percentage of patients are born with an intestinal obstruction called a meconium ileus, and another small percentage later develop liver disease (Collins, 1992). CF is caused by the mutation of a gene located on chromosome 7, which encodes for the protein Cystic Fibrosis…
