answered-by-expert Expert Answer
Nucleotides are the building blocks of polymers called polynucleotides. Each nucleotide monomer consists of a pentose (five-carbon) sugar, to which is attached two other groups; a phosphate group and a nitrogenous base.DNA molecules have two polynucleotide chains, held together in a ladder-like structure.
