mutation

(Variation and inheritance) an error in DNA replication which results in a change in an organism's genetic blueprint. Some mutations are random, others are caused by environmental factors

mutation

(Learning Modules / Biology / DNA / Glossary) Change, usually to DNA. Generally human mutations are damaging, even fatal. Occasionally they are beneficial and contribute to evolution

Mutation

In genetics, a mutation is a change of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal genetic element. Mutations result from unrepaired damage to DNA or to RNA genomes (typically caused by radiation or chemical mutagens), errors in the process of replication, or from the insertion or deletion of segments of DNA by...

Mutation

- a change in the order of nucleotide bases on a gene, which alters the configuration of the protein produced, and thus may alter the behaviour of the cell. A mutation may cause a cell to die, or become cancerous. Mutations in bacteria and viruses help them to evade detection by their hosts.

mutation

(L: mutare=to change) a sudden change in a gene, caused by a change in the molecules of DNA. The gene so changed can reproduce itself in the usual manner. If the mutation occurs in the DNA of sex cells, the mutant gene can be inherited by the offspring.

mutation

(L. mutatio from mutare to change) 1. a change in form, quality, or some other characteristic. 2. in genetics, a permanent transmissible change in the genetic material, usually in a single gene. Also, an individual exhibiting such a change. Called also (in classical genetics) a sport.

Mutation

(genetic mutation) a change in DNA from its original state. Some mutations do not cause any problems, while others result in disease; however, this term is most is often used when an individual has a genetic change that causes a health condition.

Mutation

[algebra] Right homotope and mutation are defined analogously. Since the right (p,q) mutation of A is the left (−q, −p) mutation of the opposite algebra to A, it suffices to study left mutations. If A is a unital algebra and a is invertible, we refer to the isotope by a. ==Properties== and if y is invertible this is referred to as an is...

Mutation

[genetic algorithm] Mutation is a genetic operator used to maintain genetic diversity from one generation of a population of genetic algorithm chromosomes to the next. It is analogous to biological mutation. Mutation alters one or more gene values in a chromosome from its initial state. In mutation, the solution may change entirely from the...

[Jordan algebra] In mathematics, a mutation, also called a homotope, of a unital Jordan algebra is a new Jordan algebra defined by a given element of the Jordan algebra. The mutation has a unit if and only if the given element is invertible, in which case the mutation is called a proper mutation or an isotope. Mutations were first introduce...

[knot theory] In the mathematical field of knot theory, a mutation is an operation on a knot that can produce different knots. Suppose K is a knot given in the form of a knot diagram. Consider a disc D in the projection plane of the diagram whose boundary circle intersects K exactly four times. We may suppose that (after planar isotopy) the...

Mutation

A change in a gene. Genes are really codes that tell a cell to make a particular protein. If a gene is mutated, the protein it makes will be abnormal. Mutation can also alter how a gene works by permanently switching it on or off.
