GENE MUTATION‚TYPES OF MUTATIONS 1. Gene Mutation A Gene Mutation is defined as an alternation in the sequence of nucleotides in DNA. It can affect a single nucleotide pair or larger gene segments of a chromosome. Mutations cause changes in the genetic code which lead to genetic variation and the potential to develop disease. What causes Gene Mutation? → Gene mutations are most commonly caused as a result of two types of occurrences. 1. Environmental factors Ex) chemicals‚ radiation

Gene Cloning Clone: A group of identical cells or organisms To clone a gene: 1) Insert the gene into a vector that can carry the into a host cell 2) Ensure that it will replicate there 3) Insertion is carried out by cutting the vector and the DNA to be inserted with the same restriction endonuclease to ensure that both have the same "sticky ends" Vector for cloning the bacteria come from two major types: (1) Plasmids‚ and (2) Phages Recombinant DNA Technology A) It was developed in

multiple cloning site (MCS) which is artificially implanted by adding a polylinker sequence to it. The pUC19 plasmid is also altered by inserting a gene that codes for beta-lactamase which confers resistance to the antibiotic ampicillin (Read and Strachan 2011). The MCS occupies the 5’ end of the gene lacZ (Sherwood‚ Willey and Woolverton 2012). This gene codes for only the alpha-peptide of beta-galactosidase‚ an enzyme used to break down the disaccharide lactose into glucose and galactose (Read and

How will Gene Doping effect the sports industry? Gene Doping is a different type of gene therapy that has caused a lot of controversy in the past 6-7 years due to the capability of what this method of doping could do. Gene doping therapy was started at Harvard in 1999 and was specifically used to get a substantial rise in the performance of athletes. This is done by genetically modifying cells to enhancing athletic performance. Gene therapy is done by using genes to help treat or stop diseases.

Gene and his roommate Finny (Phineas) become close friends at Devon School in the summer of 1942. Finny is always able to get away with what infractions he makes. He and Gene for a small society over jumping out of a tree into a river. They name it the “Super Suicide Society of the Summer Session”. Finny is very athletic and lures in lots of people by his charismatic behavior. He creates a game called blitzball that becomes popular within the attendees of the summer session. Gene envies Finny’s

be defined by the dominant discourses in society‚ such as gender and sexuality. Michael Foucault’s definition of discourse is more than just the ways of thinking and producing meaning through communication. The notion of discourse defined by Foucault have become closely associated with power and knowledge (Miller‚ 1990). Dominant discourse demonstrates how reality has been socially constructed. They can be found in many forms of media and communication. Discourses become dominant because they are

Gene Splicing What Is It? Gene Splicing is one type of genetic technology. It is the process of taking pieces of DNA from one or more organisms then combining them into another DNA strand to create new DNA or recombinant DNA. How does it Work? Chemicals called restriction enzymes are used as scissors to cut the DNA. Thousands of these restriction enzymes exist‚ each recognizing only a single sequence of DNA. Once it finds that sequence in a strand of DNA‚ it attacks it and splits the base pairs
