QUESTION 4

Which of the following features is common between the bacterial and eukaryotic ribosomes in translation initiation?

They both use an initiator tRNA that carries formylmethionine.

They both bind to the 5' end of the mRNA and move forward to find the start codon.

They both recognize the start codon by interacting with the Shine–Dalgarno sequence.

They both interact with various translation initiation factors.

All of the above.

catalyze loading of an anticodon onto the 3 end of a tRNA.
