A single nucleotide is made up of three components: a nitrogen-containing base, a five-carbon sugar (pentose), and at least one phosphate group With all three joined, a nucleotide is also termed a “nucleoside phosphate”. Nucleic acids are long-chain polymeric molecules, the monomer (the repeating unit) is known as the nucleotides and hence sometimes nucleic acids are referred to as polynucleotides They are composed of nucleotides, which are the monomers made of three components: a 5-carbon sugar, a phosphate group and a nitrogenous base.If the sugar is a compound ribose, the polymer is RNA (ribonucleic acid… Hence nucleic acids … Both DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are polymers of individual nucleotides.
