Question

The mutation in which a purine is replaced by pyrimidine and vice versa is known as

• A. Transversion
• B. Transition
• C. Induced mutation
• D. Transformation

Hint:

Transversion mutations are more disruptive to the DNA sequence than transition mutations due to the structural differences between purines and pyrimidines

Answer 1

The Correct Option is A

A transversion mutation occurs when a purine is substituted by a pyrimidine or a pyrimidine is substituted by a purine This contrasts with transition mutations where purines replace purines or pyrimidines replace pyrimidines
