Question

The reason for double helical structure of DNA is operation of (A) van der Waals forces (B) dipole-dipole interaction (C) hydrogen bonding (D) electrostatic attractions

Tardigrade Admin · Accepted Answer

Hydrogen bonding is involved molecular force in the DNA molecule. Watson and Crick observed the purine-pyrimidine type of hydrogen bonding (instead of purine-purine and pyridine-pyridine)
