IF-3 Is Important in the Initiation of Translation in Prokaryotic

IF-3 is important in the initiation of translation in prokaryotic cells in all EXCEPT:

A) It binds to the 30 S subunit and is required for the binding of the mRNA to this subunit.
B) Its association with the 30 S subunit prevents association with the 50 S subunit.
C) Its dissociation from the 30 S subunit permits formation of the initiation complex for translation.
D) It binds the 70 S subunit to promote binding of a new mRNA.
E) All are important.
