WebTranslation Initiation in Bacteria. Translation initiation in the bacterium E. coli includes the following (see figure 11.10): The mRNA binds to the small ribosomal subunit (30S) via the Shine-Dalgarno sequence. An initiation factor protein called IF3 promotes the formation of hydrogen bonds between the ribosome and the mRNA. WebTranscription is initiated by the attachment of a protein known as a sigma. The sigma attaches to one strand of the DNA (the template strand) at a very specific location. In …
