How does a base analog introduce a mutation
WebApr 3, 2024 · How does a base analog introduce a mutation? Base Analogues Usually, substitution of a base analogue will result in altered base pairings and structural changes that affect DNA replication and transcription of genes. WebOne group of chemical mutagens includes the base analogs. How do these lead to mutations? When replication occurs, complementary base pairing may fail because the base analog may not be treated the same way as the base that it replaced Some bacteria have unusually high mutation rates.
