the fact that a purine base always pairs through hydrogen bonds with a pyrimidine base in the DNA double helix leads to

Options

A. The antiarallel nature
B. The semiconservative nature
C. Uniform width throughout DNA
D. Uniform length in all DNA

Answer

C

Explanation

Each base pair consists of a purine and a pyrimidine. The nuclestides in a base pair are complementary which means their shapes allow them to bond together with hydrogen bones. The A – T pair form two hydrogen bonds. The hydrogen bonding between complementary bases holds the two strands of DNA together
