Answer 2

a sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA molecule.

Answer 3

Cells decode mRNAs by reading their nucleotides in groups of three, called codons. Each codon specifies a particular amino acid, or, in some cases, provides a "stop" signal that ends translation. In addition, the codon AUG has a special role, serving as the start codon where translation begins.
