So, in translation, the mRNA molecule, which itself is composed of nucleotides, is used as a template to synthesize our proteins that consist of amino acids. And here lies our problem. Nucleotides are different from amino acids, so we cannot use this complementary method. 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.
