The distance between the sugar-phosphate structures in a DNA molecule is equal to the distance of one purine and one pyrimidine molecule.

Question

Quizplus · Accepted Answer

The distance between the sugar-phosphate backbone in DNA is approximately 0.34 nm, which is the same as the distance between one purine and one pyrimidine nucleotide. This distance is known as the pitch of the DNA helix. Therefore, the statement is true.
