Mutation | Definition, Causes, Types, & Facts | Britannica
WEBApr 5, 2024 · Mutation, an alteration in the genetic material (the genome) of a cell of a living organism or of a virus that is more or less permanent and that can be transmitted to the cell’s or the virus’s descendants. The genomes of organisms are all composed of DNA, whereas viral genomes can be of DNA or RNA.
Mutations (article) | Khan Academy
WEBA mutation is any change to the nucleotide sequence of a DNA molecule. Some mutations arise as DNA is copied. Others are due to environmental factors. A mutation in a gene can change the structure and function of the protein encoded by that gene. This, in turn, can affect an organism’s traits.
Mutation - Wikipedia
WEBFour classes of mutations are (1) spontaneous mutations (molecular decay), (2) mutations due to error-prone replication bypass of naturally occurring DNA damage (also called error-prone translesion synthesis), (3) errors introduced during DNA repair, and (4) induced mutations caused by mutagens.

Mutation
WEB6 days ago · A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection. Germline mutations (that occur in eggs and sperm) can be passed on to offspring, while somatic mutations (that occur in body cells) are not passed on.

Types of mutations - Understanding Evolution
WEBTypes of mutations. There are many different ways that DNA can be changed, resulting in different types of mutation. Here is a quick summary of a few of these: Substitution. A substitution is a mutation that exchanges one base for another (i.e., a change in a single “chemical letter” such as switching an A to a G). Such a substitution could:
