Abstract

Deoxyribonucleic acid (DNA) is a polymer of nucleotides. In the cell, DNA usually adopts a double-stranded helical form, with complementary base-pairing holding the two strands together. The most stable conformation is called B-form DNA, although other structures can occur under specific conditions.
