Unreferenced date January 2008 Mutationfrequency refers to the number or frequency of cells with a specific mutation in a given population during a point in time. The phrase is often used in relation to drug resistance in bacteria l or Virus viral cultures. Mutationfrequency is related to the concept of mutation rate .

MutationFrequency Decline mfd is the gene which encodes the protein Mfd also known as Transcription Repair Coupling Factor TRCF . Mfd functions in transcription coupled repair to remove a stalled RNA polymerase that has encountered DNA damage and is unable to continue translocating. Mfd utilizes Adenosine triphosphate ATP to translocate along DNA, most likely forcing RNA polymerase forward and ultimately dissociating it from the DNA template Roberts & Park, Current Opinion in Microbiology 2004, DOI 10.1016 j.mib2004.02.014 . Mfd also contains binding domains which recruit UvrA and trigger the associated nucleotide excision repair pathway and was initially discovered when its mutation led to a decrease in mutation rates after irradiation by UV light. It has been shown that Mfd may also re initiate transcription at backtracked RNAP by forcing the polymerase forward and out of its backtracked state Park, Marr & Roberts, Cell vol 109 June 14, 2002 PMID 12086674 .

The term resistance mutation is most commonly used to describe point mutation s in virus gene s that allow the virus to become resistant to treatment with a particular antiviral drug . The term is now being seen with more frequency in bacteriology and parasitology . The term resistance mutation first appeared in the management of HIV , which was the first virus in which genome sequencing is routinely used to look for drug resistance. Nomenclature Resistance mutations are conventionally listed as a letter, number and letter. For example, the M184V mutation in the reverse transcriptase gene of HIV confers resistance to the drug lamivudine . The letters stand for amino acid s and use the traditional one letter abbreviations. M stands for methionine , and V stands for valine 184 is the number of that amino acid position counting from the amino terminus of the protein. M184V means that the 184th amino acid of the protein is normally methionine, but that a mutation in the gene for that protein produces a form of the protein where that amino acid is substituted by valine instead. The form V184 is sometimes seen this means that the 184th amino acid of that protein is valine, but it gives no information as to whether that is a mutation or the normal state of affairs. The Greek capital letter delta indicates a deletion so M184 would mean that the 184th amino acid is usually methionine, but that this position is now missing. Alternatives are separated by slashes so, M184V I means either M184V, or M184I . References references Category Mutation Pharma stub Genetics stub virus stub ... more details

A frameshift mutation also called a framing error or a reading frame shift is a genetics genetic mutation caused by indel s gene insertion insertions or genetic deletion deletions of a number of nucleotide s that is not evenly divisible by three from a DNA sequence. Due to the triplet nature of gene expression by codon s, the gene insertion insertion or genetic deletion deletion can change the reading frame the grouping of the codons , resulting in a completely different Translation genetics translation from the original. The earlier in the sequence the genetic deletion deletion or gene insertion insertion occurs, the more altered the protein produced is. A frameshift mutation will in general cause the reading of the codons after the mutation to code for different amino acids. The frameshift mutation will also alter the first stop codon UAA , UGA or UAG encountered in the sequence. The polypeptide being created could be abnormally short or abnormally long, and will most likely not be functional. Frameshift mutations frequently result in severe genetic diseases such as Tay Sachs disease . A frameshift mutation is responsible for the disabling of the CCR5 HIV receptor and some types of familial hypercholesterolemia Lewis, 2005, p. 227 228 .

Unreferenced date December 2009 In genetics , a neutral mutation is a mutation that has no effect on Fitness biology fitness . In other words, it is neutral with respect to natural selection . For example, some mutations in a DNA triplet or codon do not change which amino acid is introduced this is known as a synonymous substitution . Unless the mutation also has a Regulation of gene expression regulatory effect, synonymous substitutions are usually neutral. Some non synonymous mutations, i.e. mutations that do change the amino acid, are also neutral these neutral changes are often to a chemically similar amino acid that works just as well. Such mutations may spread through genetic drift neutral drift . Neutral mutations can accumulate over time due to genetic drift or genetic hitchhiking genetic draft . According to the neutral theory of molecular evolution , while the majority of mutations are deleterious, the majority of mutations that go on to become fixed as differences between species are neutral.

A germline mutation is any detectable and heritable variation in the lineage of germ cell s. Mutation s in these cells are transmitted to offspring , while, on the other hand, those in somatic cells are not. A germline mutation gives rise to a constitutional mutation in the offspring, that is, a mutation that is present in virtually every cell. A constitutional mutation can also occur very soon after fertilisation , or continue from a previous constitutional mutation in a parent. ref http www.daisyfund.org rb about genetics.html RB1 Genetics at Daisy s Eye Cancer Fund.
