But during the process of translation, when we synthesize our proteins from RNA molecules, things aren't that simple. And that's because our mRNA consists of nucleotides. So the language of RNA is the language of nucleotides, but proteins use the language of amino acids. And as we know, nucleotides and amino acids are not the same type of molecules. So the question is, how exactly does the cell know what sequence of nucleotides corresponds to a sequence of amino acids? So once again, things become a bit more complicated when we synthesize proteins during the process of translation, which we'll discuss in much more detail in the next several lectures.
