What is the backbone of the nucleic acid constructed of?

Question

Quizplus · Accepted Answer

The backbone of the nucleic acid is constructed of alternating sugar phosphate groups, which provide the structural support and stability for the molecule. The nitrogenous bases (adenine, guanine, cytosine, and thymine or uracil in RNA) are attached to the sugar molecules and form the "rungs" of the ladder-like structure of DNA or RNA. Amine bases are a type of nitrogenous base, but they are not part of the backbone structure. Glucose polymers and polyamides are not components of nucleic acids.
