Question

Find out why the distance between two polynucleotide chains in DNA remains almost constant?

Answer 1

HELLOOO

The bases in two strands of DNA are paired through hydrogen bond (H-bonds) and form base pairs .

Adenine forms two hydrogen bonds with Thymine from opposite strand and Thymine forms two hydrogen bonds with Thymine from the opposite strand.

 Similarly, Guanine and Cytosine are bonded with three H-bonds. As a result of these bonds, the distance between two polynucleotide chains in dna remains constant
