Determine the correctness or otherwise of the following Assertion (a) and the Reason (r): Assertion: N-methyl-N’-nitro-N-nitrosoguanidine (NTG) is an effective chemical mutagen. Reason: Mutations induced by NTG mainly are GC → AT transitions. Options: (A) both (a) and (r) are true and (r) is the correct reason for (a) (B) both (a) and (r) are true but (r) is not the correct reason for (a) (C) (a) is true but (r) is false (D) (a) is false but (r) is true
Determine the correctness or otherwise of the following Assertion (a) and the Reason (r):
Assertion: N-methyl-N’-nitro-N-nitrosoguanidine (NTG) is an effective chemical mutagen.
Reason: Mutations induced by NTG mainly are GC → AT transitions.
Options:
(A) both (a) and (r) are true and (r) is the correct reason for (a)
(B) both (a) and (r) are true but (r) is not the correct reason for (a)
(C) (a) is true but (r) is false
(D) (a) is false but (r) is true
Answer
Answer: (A) both (a) and (r) are true and (r) is the correct reason for (a)
Explanation: NTG is indeed an effective chemical mutagen and primarily induces GC to AT transitions, making both the assertion and reason correct.
