Nucleic acids are biological macromolecules. Sugar and phosphate groups form an uniform backbone (the phosphate groups are actually the acids). Variable side chains are attached to each sugar. The side chains of DNA are either of four nitrogenous bases: two purines (adenine and guanine) and two pyrimidines (cytosine and thymine). RNA comprises uracil instead of thymine.
Any one of four nitrogenous (nitrogen-containing) bases (adenine, thymine, guanine and cytosine). The sequence of the bases in DNA determines the sequence of amino acids in all proteins found in living things.

On the DNA molecule, one of the four chemical units that, according to their order and pairing, represent the different amino acids. The four bases are: adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, uracil (U) substitutes for thymine.

A cyclic, nitrogen-containing compound that is one of the essential components of nucleic acids. Exists in five main forms (adenine, A; guanine, G; thymine, T; cytosine, C; uracil, U). A and G have a similar structure and are called purines; T, C and U have a similar structure and are called pyrimidines. A base joined to a ribose sugar joined to a phosphate group is a nucleotide - the building block of nucleic acids.
The four units of DNA and RNA differ in their bases. The single molecule ring consists of a pyrimidine ring like thymine (T) and cytosine (C). The bases adenine (A) and guanine (G) belong to the group of purines and form a double ring. Instead of thymine, RNA contains another pyrimidine base, uracyle.
