What is Nucleotides

Nucleotides function as letters in the genetic alphabet. Except that, because there are only four nucleotides, which would only allow to code four different pieces of information, each genetic 'letter' is made up of three different nucleotides. Each 'letter' of three nucleotides, called a codon, corresponds to a different amino acid.
