Question

Quizplus · Accepted Answer

The secondary structure of DNA is a double helix, consisting of two polynucleotide strands held together by hydrogen bonds between complementary nitrogenous bases. The bases are on the inside of the helix, forming base pairs (adenine with thymine, guanine with cytosine) which provide stability to the double helix structure.
