Genetics, Mutagenesis - StatPearls - NCBI Bookshelf
网页2022年9月19日 · Mutagenesis is the process of an organism's deoxyribonucleic acids (DNA) change, resulting in a gene mutation. A mutation is a permanent and heritable change in genetic material, which can result in altered protein function and phenotypic changes.
Mechanisms of mutagenesis: DNA replication in the presence of …
网页Environmental mutagens cause DNA damage that disturbs replication and produces mutations, leading to cancer and other diseases. We discuss mechanisms of mutagenesis resulting from DNA damage, from the level of DNA replication by a single polymerase to the complex DNA replisome of some typical model organisms (including bacteriophage T7, T4 ...

Current trends and insights on EMS mutagenesis application to …
网页2023年1月4日 · Nasri et al. (2022) mutated four Chrysanthemum varieties (“Homa”, “Fariba2”, “Arina”, and “Delkash”) with EMS (0-0.5%) as mutagens and leaf discs as explants to obtain new varieties. In addition, ISSR and IRAP molecular markers were used to detect the genetic polymorphism between the mutant and its parents.
