This is what tells the ribosome where to start on the mRNA. It doesn't start right at the extreme end. It has to start somewhere and then go along until it finds the first ribosome. codon, the first amino acid signal to be made. And that process of initiation is very complex. And what viruses do is they shut down the host initiation. So none of the host genes can be made into protein.
