Initiation See Fig. Met-tRNA pairs with start codon of mRNA 2. Elongation See Fig. Ejection of uncharged t-RNA 4. Translocation of mRNA and peptidyl-tRNA 3.
Regulation often occurs at the transcriptional level.
Promoter is necessary for initiation transcription. DNA region near a promoter. Involved in regulation of transcription. A set of contiguous genes under the transcriptional control of a single promoter. Regulatory Mechanisms I. Negative regulation.
