- 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)
- 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
- 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
- Mutations - Understanding Evolution

- What Are Genetic Mutations, Their Causes, and Effects?
A mutation is like a change in this recipe, such as a misplaced ingredient or an altered instruction These changes can range from a single “letter” (nucleotide) being swapped for another, to much larger modifications involving entire segments of the genetic code
