Nucleic acids are made up of nucleotides. Each nucleotide is composed of a sugar + a phosphate + a nitrogen base. The nitrogenous bases are Adenine which pairs with Thymine and Cytosine which pairs with Guanine.Nucleotide polymers, (chains of nucleotides) are made up of nucleotides linked to the-OH group on the 3' carbon of one nucleotide and the phosphate on the 5' of the following nucleotide.The two chains in a double helix run antiparallel to one another. 8 people found this useful. Answered. nucleotide is a monomer of a nucleic acid consisting of 3 parts.  These 3 parts include a pentose sugar, a phosphate  group, and a nitrogenous base. The nitrogenous bases â¦  include purines (adenine and guanine) and pyrimidines (cytosine and  thymine).
1 Nucleic acids (DNA and RNA) are long polymers made of repeating units of nucleotides. 2  Nucleotide units are made of phosphate-sugar-nitrogenous base units. 3  The nitrogenous bases found in DNA are adenine, guanine, cytosine and thymine. 4  Adenine and guanine are purine bases while cytosine and thymine are pyrimidnes.
