What are the two main sections of the DNA molecule?

Answer 1

There are three main section of a DNA molecule.

The nitrogenous bases. Four in number. Guanine linked to cytosine and thymine linked to adenine.

The deoxyribose sugar.

The phosphate group backbone.

Answer 2

The two main sections of the DNA molecule are the sugar-phosphate backbone and the nitrogenous bases. The sugar-phosphate backbone consists of alternating sugar and phosphate molecules that form the structural backbone of the DNA molecule. The nitrogenous bases (adenine, thymine, cytosine, and guanine) are connected to the sugar molecules and form the internal structure of the DNA molecule through complementary base pairing.

Answer 3

deoxyribose phosphate nitrogen base
