Vedclass · Answer

(C) The $DNA$ molecule maintains a uniform diameter of approximately $20 	ext{ Å}$ throughout its length.This uniformity is primarily due to the specific base pairing rules proposed by Watson and Crick.In $DNA$, a purine (a double-ring structure, such as Adenine or Guanine) always pairs with a pyrimidine (a single-ring structure, such as Thymine or Cytosine).Because a purine is always paired with a pyrimidine, the total width of the base pair remains constant (one double ring + one single ring = three rings total), which ensures the uniform diameter of the $DNA$ double helix.

The $DNA$ molecule has a uniform diameter due to which of the following?
