Answer:
DNA is a polymer. The monomer units of DNA are nucleotides, and the polymer is known as a "polynucleotide." Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group

Answer:
In a polymer these nucleotides form a backbone with the phosphate and sugar groups. The nitrogenous bases protrude from that backbone. RNA is a single strand. DNA is a double strand in which the nitrogenous bases pair up between two backbones
The nucleotides have a similar structure with three 'subunits':
A phosphate group
A sugar group : deoxyribose in DNA and ribose in RNA
A nitrogenous base : adenine, cytosine, guanine, thymine or uracil
