How many base pairs are there in every helical turn of Watson-Crick double helix model?
A32.3
B11.6
C20
D10.4
Answer:
D. 10.4
Read Explanation:
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.
