Mutagens (HSC SSCE Biology): Flashcards

Environmental agent that can alter DNA and cause mutations

Process of inducing mutations through external agents

Chemical, naturally occurring, and physical mutagens

Alcohol, tar in tobacco smoke, benzene, asbestos

Forms in stomach when nitrites combine with amines

Adjacent thymine or cytosine bases bonded together by UV

Radiation with enough energy to break chemical bonds in DNA

Produced when high-energy electrons interact with water

Damaged base removed from sugar linkage and replaced

DNA polymerase checks and corrects replication errors
