Number of nitrogenous bases in a codon is

Solution

The codon is set of 3 pairs of nitrogen bases. Three bases actually code for an amino acid but the DNA requires that the three bases that are doing the coding are linked to their pair. A-T, T-A, G-C. C-G.

So it takes six nitrogen bases to code for one amino acid. So a codon codes for an amino acid and requires a total of six nitrogen bases.
