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.

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.

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.

What Is a Genetic Mutation? Definition & Types - Cleveland Clinic
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.

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.

There are other types of mutations as well, but this short list should give you an idea of the possibilities.

What Is Genetic Mutation and Is It Always Bad?
A genetic mutation is any permanent alteration in the DNA sequence that makes up a gene. These changes can be tiny—affecting just a single nucleotide—or massive, involving large sections of chromosomes.
