Unreferenced date October 2010 Frameshift is a progressive rock Progressive metal metal band led by Henning Pauly . The first album, Unweaving the Rainbow is a concept album based on the work of Richard Dawkins , a scientist and writer, and features Dream Theater vocalist James LaBrie . The second concept album, An Absence of Empathy , features Sebastian Bach and back up singers. Henning Pauly has stated on his site that a future Frameshift album will also be adapted from a Richard Dawkins book, The God Delusion , but will feature two vocalists, Pauly has stated that they are Magali Luyten from Belgium Virus IV , Beautiful Sin , Ayreon and Dan Swano from Sweden Nightingale, Edge of Sanity, Ayreon and many more . Before that album is done, however, an album entitled Loading Oakfield featuring Knockdown Industries vocalist Alexander Froese will be released. Pauly has stated that this album will not be a concept album. Although both albums were supposed to be out in 2010, as of late 2011, the albums remain unreleased.

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.

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 drugs lamivudine and emtricitabine. 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
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. Many or even most mutations to noncoding DNA are neutral.

Multiple issues cleanup May 2009 context May 2009 unreferenced May 2009 orphan February 2009 Mutation Sensation is a recycling project based on reusing discarded stuffed animals toys. The concept has become an evolutionary project that reconstructs the way people think about the market economy in reference to mass production of toys, in this case which symbolizes the early education of abundance as pleasure. It is also awakening an avenue that opens eyes to the possibilities of alternative equal rights relations between the producers and the consumers of the world. With respect to the inequality of the market, the 1st Mutation Sensation session occurred during a festival under various gamey stipulations such as long hours, unfavourable work conditions and no pay. It was an intense lesson as to how much work is involved in sewing toys. Somewhere on the line, someone is suffering market demands. The Mutations have continued to develop amongst recycling festivals and childhood ecological recycling projects.

In genetics , a founder mutation is a mutation that appears in the DNA of one or more individuals who are founders of a distinct population. Founder mutations initiate with changes that occur in the DNA and can get passed down to other generations. ref name BSCS cite web url http bscs.org pages curriculumdevelopment onco glossary.htm title Bioinformatics Glossary publisher bscs.org accessdate 2009 03 23 ref ref name CIHR cite web url http www.mshri.on.ca colorectalcancer definitions.html title Colorectal Cancer Research Definitions publisher www.mshri.on.ca accessdate 2009 03 23 ref Founder mutations originate in long stretches of DNA on a single chromosome indeed, the original haplotype is the whole chromosome. As the generations progress, the proportion of the haplotype that is common to all carriers of the mutation is shortened due to genetic recombination . This shortening allows scientists to roughly estimate the age of the mutation. ref name SCIAM cite web url http www.sciam.com article.cfm?id founder mutations title Founder Mutations Scientific American publisher www.sciam.com accessdate 2009 03 23 ref References references genetics stub Category Evolutionary biology Category Genetics Category Mutation fa ... more details
