What is muitation?

Answer 1

Mutation refers to a permanent alteration in the DNA sequence of an organism's genome. These changes can occur naturally during DNA replication or be induced by environmental factors, such as radiation or chemicals. Mutations can affect a single nucleotide (point mutations) or larger segments of DNA, leading to variations in traits that can be beneficial, neutral, or harmful. In the context of evolution, mutations are a source of genetic diversity, providing raw material for natural selection.
