Question

In the double helix model of DNA as proposed by Watson and Crick, each base pair is how far from the next base pair?

• A. 0.034 nm
• B. 0.34 nm
• C. 3.4 nm
• D. 34 nm

Answer 1

Answer: (B)

0.34 nm

The distance between the two base pairs of DNA is 3.4 Angstroms.

A base pair is one of the pairs A-T or C-G, that each base pair consists of a purine and a pyrimidine. The nucleotides in a base pair are complementary which means they can bond together with hydrogen bonds.

So, the correct option is '0.34 nm'
