- 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

- 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

- Genetic Mutations: Types, Causes, and Cellular Repair Mechanisms
Genetic mutations are changes in the DNA sequence that can significantly affect an organism’s health and development These alterations can occur spontaneously or be induced by environmental factors, leading to outcomes ranging from benign variations to serious genetic disorders
- Mutation Definition - BYJUS
A population can acquire new alleles through mutations, increasing the genetic diversity of the population For mutations to impact an organism’s offspring, they must: 1) arise in cells that give rise to the succeeding generation; and 2) alter the genetic code
