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. The genomes of organisms are all composed of DNA, whereas viral genomes can be of DNA or RNA.

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 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.

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 Genetic Mutation? Definition & Types - Cleveland Clinic
Both parents need to pass the same genetic mutation onto their child for their child to inherit the mutation. Sickle cell disease is an example of a condition inherited in this pattern. X-linked dominant. Babies have an X chromosome. Only one mutation on the X chromosome needs to pass from one parent to the child for the child to inherit the ...

What Is a Genetic Mutation and Why Does It Matter?
When a mutation occurs in a germ cell and is passed to offspring, it becomes part of that individual’s genome. If the mutation improves survival or reproduction, it may spread through the population over generations.

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.

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.
