Question

Distance between two consecutive base pairs of DNA is \rule{2cm}{0.1mm}

• A. 34 nm
• B. 0.34 nm
• C. 0.34 $\times$ 10$^{-9}$ m
• D. both B \& C

Hint:

DNA has 10 base pairs per helical turn, spanning 3.4 nm, so each base pair is 0.34 nm apart.

Answer 1

The Correct Option is D

In the DNA double helix, the distance between two consecutive base pairs is approximately 0.34 nanometers (nm).
This is equal to \( 0.34 \times 10^{-9} \, \text{m} \).
Hence, both options (B) and (C) are correct.
