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.

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.

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 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.

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.

2.9: Mutations - Biology LibreTexts
Here we describe the origin of mutations, their effects on gene expression, and their ultimate role in evolution.

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.

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.
