How Does the Eukaryotic Initiation Complex Locate the True Start

Multiple Choice

How does the eukaryotic initiation complex locate the true start codon?

A) The true start codon is the first ATG encountered downstream of the Shine-Dalgarno sequence.
B) The initiation complex moves the small ribosomal subunit through the 5′ UTR, scanning for the start AUG.
C) The preinitiation complex moves the ribosome through the 3′ UTR, scanning for the Kozak sequence.
D) The true start codon is the first ATG encountered downstream of the Kozak sequence.
E) The true start codon is the formyl-ATG, which will encode for fMet in the protein.
