NEET Botany DNA Structure MCQ Question
Type: MCQ-diagram based-Hard-Class 12
A diagram shows a segment of DNA with sequences labeled as 'A', 'T', 'G', and 'C'. If the segment is 10 base pairs long, what total length in nanometers would the segment have, given the distance between consecutive base pairs in the DNA double helix?
A
4 nm
B
34 nm
C
0.34 nm
D
10 nm
Correct Answer
Option B
Detailed Explanation
According to the NCERT context, the distance between two consecutive base pairs in a DNA double helix is 0.34 nm. For a segment of 10 base pairs, the total length would be 10 × 0.34 nm = 3.4 nm.
