During the initiation of prokaryotic translation,a defect in IF3 function would generate:
A)inefficient association of the 30S and 50S subunits.
B)proteolysis of the 50S subunit.
C)an inability of tRNA and mRNA binding to the 30S subunit.
D)premature association of the 30S and 50S subunits.
E)normal progression of translation (no defect).

IF3 (Initiation Factor 3) in prokaryotes prevents the premature association of the 30S and 50S ribosomal subunits. A defect in IF3 would therefore lead to premature association of these subunits, hindering the proper initiation of translation.
