Type: MCQ-numerical-Medium-Class 12
If the distance between two consecutive base pairs in a DNA helix is 0.34 nm, what would be the approximate length of a DNA molecule with 3.3 × 10^9 base pairs?
A
122 meters
B
32 meters
C
54 meters
D
76 meters
Correct Answer
Option A
Detailed Explanation
The length of a DNA molecule can be calculated by multiplying the total number of base pairs by the distance between consecutive base pairs: 3.3 × 10^9 bp × 0.34 × 10^-9 m/bp = 1.122 meters.
