Which of the following describes an accurate order of events in<br/>translation?() A: Ribosomal translocation occurs before the first aminoacyl-tRNA<br/>molecule binds to the small subunit. B: Initiation of translation occurs only after the small subunit<br/>dissociates from the mRN C: The large subunit of the ribosome binds the mRNA before the small<br/>subunit. D: The first aminoacyl-tRNA molecule binds to the small subunit before<br/>the large subunit binds.
