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] Viral genomes contain either DNA or RNA.

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 Mutation? - University of Utah
We often refer to a mutation as a thing—the genetic variation itself. This approach can be useful when it comes to a gene associated with a disease: the disease allele carries a mutation, a DNA change that compromises the protein's function.

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.

What Is a Genetic Mutation and Why Does It Matter?
A genetic mutation occurs when there is a change in the DNA sequence. These changes can be caused by errors in DNA replication, environmental factors like radiation or chemicals, or inherited from a parent.

What is a mutation and what causes mutations? - YourGenome
A mutation is a change that occurs in our DNA sequence. This can be caused by normal processes inside the cell or by environmental factors, such as UV light.

Mutation – Types, Causes, Mechanisms, Agents, Importance
Mutation is a permanent change in the DNA sequence of a gene or chromosome, which can result from errors in replication or environmental factors and can affect an organism’s traits.
