mutagenesis
含义: The process by which the genetic material of an organism is permanently altered, resulting in a mutation. It can occur naturally or be induced deliberately in laboratory settings.
Mutagenesis may be caused by radiation, chemical agents, or errors in DNA replication. In research, site-directed mutagenesis is a powerful technique for studying gene function by introducing specific changes to a DNA sequence. The term is fundamental to genetics, molecular biology, and toxicology.
