Units of heredity

Double helix made up of two nucleic acid polymers that wrap around each other

Purines

Benzene rings with nitrogen substituted for carbons 1 and 3

A nitrogenous base, a sugar molecule and one or more phosphate groups

Benzene rings with nitrogen substituted for carbons 1 and 3 and have imidazole rings attached to them

The 3'OH of sugar of one nucleotide is linked to the phosphate group on the 5'OH of the adjacent sugar. The chain has two ends 5' and 3'
