Mutation | Definition, Causes, Types, & Facts | Britannica
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.

Mutation - Wikipedia
In biology, a mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. [1] . Mutations result from errors during replication, mitosis, meiosis, or damage to DNA, which then may trigger error-prone repair [2] or cause an error during replication (translesion synthesis).

Mutation – Types, Causes, Mechanisms, Agents, Importance

Genetic Mutation: Definition, Types, Functions, and More - Health
A genetic mutation is an alteration in the genetic code found in DNA. Mutations can be harmful, neutral, or helpful and play a role in evolution.

Mutations – Introductory Biology
The term mutation simply means a change or alteration. In genetics, a mutation is a change in the genetic material – DNA sequence – of an organism. By extension, a mutant is the organism in which a mutation has occurred. But what is the change compared to? The answer to this question is that it “depends”. The comparison can be made with the direct progenitor (cell or organism) or to ...

Mutations: Introduction, Types, Causes and Repair Mechanisms
Such mutations usually involve a change in or disruption to a base sequence in the DNA, especially in a gene. The result is the synthesis of a miscoded mRNA and ultimately a change in one or more amino acids found in the polypeptide during translation.
