which relationship about nucleotide composition in dna is correct?
The two DNA strands are termed polynucleotides since they are composed of simpler monomer units called nucleotides. Each nucleotide is composed of one of four nitrogen-containing nucleobasesâcytosine (C), guanine (G), adenine (A), or thymine (T)âa sugar called deoxyribose, and a phosphate group.
