Now let's move on to transfer RNA or tRNA. So transfer RNA makes up about 15% of the total cellular RNA found inside our cells. And tRNA has this distinct stem loop shape that we spoke about previously. And what the function of tRNA molecule is, is to basically take an activated amino acid found in the cytoplasm and bring it to the ribosil to help synthesize that polypeptide chain. And each amino acid has at least one tRNA molecule made specifically to carry and bring that amino acid to that ribosome to synthesize the protein. Now ribosomal RNA or RNA is the major component.
