NEET Botany DNA Structure MCQ Question
Type: MCQ-numerical-Medium-Class 12
If the distance between consecutive base pairs in a DNA double helix is 0.34 nm, what is the total length of a DNA molecule with 10,000 base pairs?
A
4 micrometers
B
0.34 micrometers
C
34 nanometers
D
4 nanometers
Correct Answer
Option A
Detailed Explanation
The total length of the DNA molecule can be calculated by multiplying the number of base pairs by the distance between them: 10,000 base pairs × 0.34 nm/base pair = 3400 nm, which equals 3.4 micrometers.
