Vedclass · Answer

(B) The $X$-ray diffraction data produced by Maurice Wilkins and Rosalind Franklin provided crucial information about the structure of $DNA$.According to the Watson-Crick model of $DNA$,which is based on this diffraction data,the $DNA$ molecule exists as a double helix.The distance between the two strands of the $DNA$ helix is constant and is measured as $20\ \mathring{A}$ (or $2\ nm$).Therefore,the diameter of the $DNA$ helix is $20\ \mathring{A}$.

Wilkins' $X$-ray diffraction data of $DNA$ shows the diameter of the $DNA$ helix to be:
