mutation
\mu*ta"tion\ (?), n.
1. (biol.) gradual definitely tending variation, such as may be observed in a group of organisms in the fossils of successive geological levels.
2. (biol.) (a) as now employed (first by de vries), a sudden variation (the offspring differing from its parents in some well-marked character or characters) as distinguished from a gradual variations in which the new characters become fully developed only in the course of many generations. the occurrence of mutations, and the hereditary transmission, under some conditions, of the characters so appearing, are well-established facts; whether the process has played an important part in the evolution of the existing species and other groups of organisms is a disputed question. (b) the result of the above process; a suddenly produced variation.

mutation
Any change in the DNA of a cell. Mutations may be caused by mistakes during cell division, or they may be caused by exposure to DNA-damaging agents in the environment. Mutations can be harmful, beneficial, or have no effect. If they occur in cells that make eggs or sperm, they can be inherited; if mutations occur in other types of cells, they are not inherited. Certain mutations may lead to cancer or other diseases.

Mutation
Process in which a gene undergoes a permanent, heritable structural change. A relatively permanent change in hereditary material involving either a physical change in chromosome relations or a biochemical change in the codons that make up genes; also: the process of producin a mutation. An individual, trait or strain, resulting from mutation

MUTATION
In biology, a sudden change in a gene or unit of hereditary material that results in a new inheritable characteristic. In higher animals and many higher plants, a mutation may be transmitted to future generations only if it occurs in germ -- or sex cell -- tissue; body cell mutations cannot be inherited. Changes within the chemical structure of single genes<!-- (see) --> may be induced by exposure to radiation, temperature extremes, and certain chemicals. The term mutation may also be used to include losses or rearrangements of segments of chromosomes, the long strands of genes. Mutation, which can establish new traits in a population, is important in evolution. As related to HIV: During the course of HIV disease, HIV strains may emerge in an infected individual that differ widely in their ability to infect and kill different cell types, as well as in their rate of replication. Of course, HIV does not mutate into another type of virus.

Mutation
In biology, a change in a gene or structure or number of chromosomes. It constitutes genetic noise in the intergenerational transmission of genetic information. In evolution , mutation is the ultimate source of inheritable variation. (Krippendorff )

Mutation
In biology, mutations are changes to the base pair sequence of the genetic material of an organism. Mutations can be caused by copying errors in the genetic material during cell division, by exposure to ultraviolet or ionizing radiation, chemical mutagens, or viruses, or can occur deliberately under cellular control during processes such as hypermutation. In multicellular organisms, mutations can be subdivided into germ line mutations, which can be passed on to descendants, and somatic mutations, which cannot be transmitted to descendants in animals. Plants sometimes can transmit somatic mutations to their descendants asexually or sexually (in case when flower buds develop in somatically mutated part of plant). A new mutation that was not inherited from either parent is called a de novo mutation.
