Botany-Genetic Code
NEET Botany Genetic Code Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): Insertion or deletion of three nucleotides in a DNA sequence does not alter the reading frame of the genetic code. | Reason (R): A change in the reading frame requires the insertion or deletion of a number of nucleotides not divisible by three.
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.
Correct Answer
Option A
Detailed Explanation
Both statements are true. The reading frame of the genetic code is maintained when an insertion or deletion involves a multiple of three nucleotides, as the deletion or insertion affects entire codons without shifting the frame.
