So how exactly does the cell know what sequence of nucleotides corresponds to what sequence of amino acids? So what the cell actually does is it translates the language of our nucleotides, our mRNA molecule, to the language of our proteins, our amino acids, by using a system known as the genetic code. So basically, the ribosomes of the cell use our RNA molecule, use our genetic code to translate the sequence of nucleotides in the mRNA molecule to the sequence of amino acids. 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.
