WebThe process of protein synthesis in E. coli involves the following steps: 1. Transcription: The partial uncoiling of two DNA strands occurs. This is followed by the production of single stranded mRNA on one of the two DNA strands. The messenger RNA complement is made in accordance with base pairing rules. Web25 nov. 2004 · In eukaryotes, initiation of translation is generally dependent on the presence of a 5' cap structure on the messenger RNA. Cap-dependent translation initiation is a complex process, facilitated by a large number of initiation factors (eIFs) that form a complicated network of cooperative interactions with the 40S ribosomal subunit.
