Translation Process Quiz

What is the role of the initiator tRNA during translation?

• It binds to the stop codon.

• It attaches to the start codon AUG.

• It releases the polypeptide chain.

• It dissociates the ribosome.

Where does the tRNA transfer its amino acid during translation?

• E site

• A site

• P site

• R site

What happens when a release factor binds during translation?

• The ribosome starts translation.

• The polypeptide chain is elongated.

• The ribosome and polypeptide chain dissociate from the mRNA.

• The tRNA binds to the A site.

In which direction does the ribosome move along the mRNA during translation?

• 3' → 5'

• 5' → 3'

• 2' → 4'

• 4' → 2'

What is the function of the E site in the ribosome during translation?

• It binds the initiator tRNA.

• It releases the deacylated tRNA.

• It holds the growing polypeptide chain.

• It binds the release factor.
