Mutagenesis is the entire process of producing a genetic mutation. This may arise spontaneously or be induced by mutagens. Researchers also use a number of approaches to generate mutations, including transposon mutagenesis to create random gene knockouts, and site-directed mutagenesis, which utilises the polymerase chain reaction to introduce distinct mutations. https://waylonqxafi.blogacep.com/27123528/helping-the-others-realize-the-advantages-of-mutagenesis
