- Binding on IF1 & IF3 to an empty 70S ribosome dissociates it into 50S and 30S subunits.
- (a)5' region of mRNA binds to free 30S ribsomal subunit, IF3 is released................... (b)Initiator fMet-tRNAfMet carried by IF2-GTP binds to P site of 30S ribsomal subunit.
- Free 50S ribosomal subunit binds, IF1 & IF2-GDP + Pi are released. Certain details of the process remain uncertain. For example, the exact order of binding of IF1, IF2, IF3, tRNA, and mRNA is unclear.
