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 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 Mutation? Understanding DNA Changes and Their Impact on Life
To understand mutation is to appreciate both the fragility and resilience of life. It reveals how a single letter change in a molecule can alter the course of history—or the fate of an individual.

Mutations - Understanding Evolution
Mutations can be beneficial, neutral, or harmful for the organism, but mutations do not “try” to supply what the organism “needs.” In this respect, mutations are random — whether a particular mutation happens or not is unrelated to how useful that mutation would be.

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 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.
