How is a mutation induced by the mutagen? Explain with examples.
Answers
Answer:
Mutagens induce mutations by a variety of mechanisms. Some mutagens mimic normal bases and are incorporated into DNA, where they can mispair. Others damage bases and either cause specific mispairing or destroy pairing by causing nonrecognition of bases.
Explanation:
Induced mutations are alterations in the gene after it has come in contact with mutagens and environmental causes. Alkylating agents (e.g., N-ethyl-N-nitrosourea (ENU). These agents can mutate both replicating and non-replicating DNA.
Answer:
Mutagens are the substances that alter the genetic material that is deoxyribonucleic acid which is passed on from parents to offspring. Mutagens can be physical,chemical and biological.Mutagens are chemical compounds or forms of radiation (such as ultraviolet (UV) light or X-rays) that cause irreversible and heritable changes (mutations) in the cellular genetic material, deoxyribonucleic acid (DNA)
