The distance between two polynucleotide chains in DNA remain almost same because it follow the point that purine always connect with pyamidrine by hydrogen bond.

Rohit Krishna 5 years, 5 months ago

Also,the nitrogenous bases are arranged in a way such that purines are always opposite to pyrimidines and hence a constant pairing with equal intervals in between is present.
