Vedclass · Answer

(D) The width (diameter) of a standard $B-DNA$ double helix is constant regardless of the number of turns.In a $B-DNA$ molecule,the distance between the two strands is approximately $20\,\mathring{A}$ $(2\,	ext{nm})$.Since the width is a structural property of the helix diameter and not dependent on the length (number of turns),the width remains $20\,\mathring{A}$ for any number of turns.

What is the width of a $DNA$ molecule having five turns?
