Botany-Genetic Code
NEET Botany Genetic Code Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): The genetic code is unambiguous, meaning that a particular codon will always code for the same amino acid. | Reason (R): Because of mutations, the genetic code can change the amino acid sequence during translation.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false but R is true.
Correct Answer
Option C
Detailed Explanation
The genetic code is unambiguous as a given codon always codes for the same amino acid. The reason (R) is incorrect because mutations do not change the property of the genetic code being unambiguous; they might alter the sequence but not the intrinsic nature of the codon-to-amino acid assignment.
