So the genetic code basically is the link between the sequence of nucleotides and our sequence of amino acids. Now, what exactly does our genetic code actually consist of? Well, basically, the genetic code is a list of codons. And a codon is basically a series of three consecutive nucleotides, where each codon corresponds to specific type of amino acids. So in the mRNA molecule, a series of three consecutive nucleotides, known as our codon, corresponds to some specific amino acid. For example, the sequence of nucleotides, our guanine, uracil.
