Question

The initiator tRNA occupies which site on the ribosome?
A:peptidyl site 
B: aminoacyl site 
C:initiator site

anonymous · Answer

At this stage, the initiator aminoacyl tRNA occupies one binding site, the P-site (peptidyl site), on the ribosome, while a second tRNA binding site (the A-site, or aminoacyl site) is free to accept the next aminoacyl tRNA molecule. In the subsequent steps, the elongation process aminoacyl tRNA molecules are brought to the A-site as ternary complexes together with guanosine triphosphate (GTP) and a protein factor (elongation factor Tu).

The answer is A
