Answer
A nucleic acid is a polymer of nucleotides. Each nucleotide consists of a pentose sugar (5 carbon sugar), a phosphate group and a nitrogenous base.
Work Step by Step
There are two types of nucleic acids:
1. DNA: the nucleotide of this consists of deoxyribose sugar (a pentose sugar), a phosphate group and nitrogenous base. There are 4 types of bases found in DNA: Adenine, Thymine, Cytosine and Guanine.
2. RNA: a nucleotide of RNA consists of ribose sugar (a pentose sugar), a phosphate group and a nitrogenous base. The bases are of 4 types: Adenine, Uracil, Cytosine and Guanine.
