Mutation rate — In genetics, the mutation rate is the chance of a mutation occurring in an organism or gene in each generation (or, in the case of multicellular organisms, cell division). The mutation frequency is the number of individuals in a population with a … Wikipedia

mutation — Any change in the sequence of genomic DNA. This may result from one or many base pair changes. A change in a gene resulting in the formation of another allele … Forensic science glossary
Adaptive mutation — Evolutionary theory describes that mutagenesis occurs randomly, regardless of the utility of a genetic mutation to the organism. If it is beneficial or neutral, the organism will survive to reproduce and pass on the mutation. However, molecular… … Wikipedia
Point mutation — 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… … Medical dictionary
chromosomal mutation — a mutation affecting large regions of a chromosome and caused by breakage, e.g., by deletion, inversion, or translocation. See also genomic m. and point m … Medical dictionary

Oligomer restriction — (abbreviated OR) is a procedure to detect an altered DNA sequence in a genome. A labeled oligonucleotide probe is hybridized to a target DNA, and then treated with a restriction enzyme. If the probe exactly matches the target, the restriction… … Wikipedia
