Coupled transcription and translation - Ribosomes bind mRNA while mRNA is still being created, so that translation begins while transcription is still occurring - Advantage of lacking a nucleus Translation initiation - - Initiation factors bind ribosome to the ribosome binding site known as the Shine Delgarno sequence (AGGAGG) - Begins at start codon 1. 30s subunit binds mRNA 2. IF2 interacts with initiator tRNA 3. fMet-tRNA binds to start codon 4. Association of initiator tRNA with ...
