Mutation
101Mutation, germline — A heritable change in the DNA that occurred in a germ cell (a cell destined to become an egg or in the sperm) or the zygote (the conceptus) at the single cell stage. When transmitted to a child, a germline mutation is incorporated in every cell… …
102Mutation, point — A single nucleotide base change in the DNA. A point mutation may consist of the loss of a nucleotide, the insertion of an additional nucleotide, or the substitution of one nucleotide for another. The first point mutation discovered in humans… …
103Mutation, somatic — A change in a gene or chromosome that occurs in a general body cell, as opposed to a germ cell, and so cannot be transmitted to children. A somatic mutation occurs in a single cell after the conception of the individual. That change is then… …

105mutation rate — The frequency with which a particular mutation appears in a population or the frequency with which any mutation appears in the whole genome of a population. Normally the context makes the precise use clear. See fluctuation analysis …
106Mutation, nonsense — A mutation (a change) in a base in the DNA that prematurely stops the translation (reading) of messenger RNA (mRNA) resulting in a polypeptide chain that ends prematurely and a protein product that is truncated (abbreviated) and incomplete and… …
107Mutation, null — A mutation (a change) in a gene that leads to its not being transcribed into RNA and/or translated into a functional protein product. For example, a null mutation in a gene that usually encodes a specific enzyme leads to the production of a… …
