A mutation is a change or alteration in the DNA sequence of an organism. It can occur naturally due to errors during DNA replication or as a result of exposure to mutagenic agents, such as radiation or chemicals.
Mutations can have various effects on an organism, ranging from being insignificant or even beneficial to causing genetic diseases or disorders.
Mutations are the basis of genetic variability and species evolution, as they can lead to new characteristics or adaptations that enable survival in changing environments.
