In fact, because of this, because the mRNA molecule in prokaryote cells does not have to be modified in any way following the process of transcription, translation usually begins on that mRNA molecule before it is actually synthesized. And this is in contrast to how it takes place inside our cells, inside eukaryotic cells, so inside bacterial cells and many other prokaryotic cells translation the process of protein synthesis begins on that mRNA molecule before that mRNA molecule is actually completely synthesized. And that's because the newly synthesized mRNA molecule in prokaryotic cells consists of a continuous sequence of codons. So if blue means we have these codons, then the entire mRNA molecule in prokaryotic cells consists of this blue region because these blue regions are the codons that express that particular sequence on the polypeptide chain. Now, for quite some time we thought the same exact thing was true in eukaryotic cells such as human cells. But in 1977, Philip Sharp and Richard Roberts basically discovered that this was not true when it came to mRNA in eukaryotic cells.
