Mutation - Wikipedia
WEBIn biology, a mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. [1] Viral genomes contain either DNA or RNA.
Mutation | Definition, Causes, Types, & Facts | Britannica
WEBAug 16, 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.
What is a Genetic Mutation? Definition & Types - Cleveland Clinic
WEBA genetic mutation is a change to a gene’s DNA sequence to produce something different. It creates a permanent change to that gene’s DNA sequence. Genetic variations are important for humans to evolve, which is the process of change over generations. A sporadic genetic mutation occurs in one person.

Mutation - Definition and Examples - Biology Online Dictionary
WEBA mutation is a change in the nucleotide sequence of a gene or a chromosome. Based on the effect of mutation on the gene structure, mutations are (1) small-scale or (2) large-scale. Small-scale mutations are a type of mutation where one or a few nucleotides of a gene are affected.
Genetic Mutations | Types of Mutations - American Cancer Society
WEBSome people have changes in the nucleotides of a gene, which are known as variants (or mutations). For example, one nucleotide ‘letter’ might be switched for another, or one or more letters might be missing, when compared to most other people’s genes. Gene variants can have different effects on the proteins they code for. For example:
