Sentences with word «mutagenesis»
Mutagenesis refers to the process of creating changes or mutations in the genetic material (DNA) of an organism. These changes can occur spontaneously or be induced by various external factors, such as chemicals, radiation, or certain biological agents. Mutagenesis plays a critical role in evolution, genetic research, and the development of new traits in organisms. Full definition
