And before we can actually synthesize the proteins from that premRNA molecule we have to modify that pre mRNA molecule to produce the fully mature and functional mRNA molecule and only then can we actually synthesize the proteins. And unlike in prokaryotic cells in eukaryotic cells a distinct mRNA molecule is produced for every one of the genes that is found on the DNA molecule. And the messenger RNA molecule makes up about 5% of the total RNA composition found in our cell. 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.
