Question

How many base pairs are there in every helical turn of Watson-Crick double helix model?

• A. 32.3
• B. 11.6
• C. 20
• D. 10.4

Answer 1

Answer:

D. 10.4

Watson-Crick double helix model consists of 10.4 base pairs per helical turn. Since one helical turn formed by 360° and there would be 34.3° twist angle per residue among adjacent base pair.
