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
A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses.

What Is a Mutation? Definition, Types, and Examples
A mutation is a change in the sequence of DNA, the molecular instruction manual inside your cells. It can be as small as a single letter of genetic code swapping for another, or as large as an entire chunk of DNA being deleted or rearranged.

A genetic mutation changes the information your cells need to form and function. Your genes are responsible for making proteins that tell your body what physical characteristics you should have.

Mutation – Types, Causes, Mechanisms, Agents, Importance
What is Mutation? Mutation refers to a permanent alteration in the DNA sequence of a gene or chromosome. This change can occur due to intrinsic factors, such as errors during DNA replication, or extrinsic factors, including exposure to environmental elements like UV light.

Genetic Mutations- Definition, Types, Causes and Examples
Any alteration in a nucleotide sequence of DNA is called as a mutation. Chromosomal, conditional and gene mutations are some of the examples of different type of Genetic mutations.
