- 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; see heredity: The physical basis of heredity )
- 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
- Mutation - Definition, Types, Examples and Quiz - Biology Dictionary
In biology, mutations refer to changes in chromosomes and genes, which typically manifest physically The effect of a mutation can depend on the region in which the sequence of genetic material has been changed

This page discusses DNA mutations in living cells, their types (point mutations, indels, etc ), and diseases associated with them, like sickle cell anemia It highlights the role of mutations in …
- Mutation – Types, Causes, Mechanisms, Agents, Importance
Mutations can be categorized broadly into two types: gene mutations and chromosome mutations Gene mutations involve changes in the nucleotide sequence of a gene, affecting its allele Chromosome mutations, on the other hand, involve alterations in chromosome structure, including changes to chromosome segments, whole chromosomes, or even entire
- Types of mutations - Understanding Evolution
There are many different ways that DNA can be changed, resulting in different types of mutation Here is a quick summary of a few of these: A substitution is a mutation that exchanges one base for another (i e , a change in a single “chemical letter” such as switching an A to a G) Such a substitution could:
