WebbThe phenomenon of internal initiation of translation was discovered in 1988 on poliovirus mRNA. The prototypic cis-acting element in the 5′ untranslated region (5′UTR) of poliovirus mRNA, which is able to direct initiation at an internal start codon without the involvement of a cap structure, has been called an IRES (Internal Ribosome Entry Site or Segment). WebbThe assembly produces two subunits of a ribosome—the large and the small subunits. These subunits then leave the nucleus through pores in the nuclear envelope. At the start …
