Translation Process Quiz

What is the role of the initiator tRNA in translation?

• It binds to the stop codon.

• It carries the first amino acid to the ribosome.

• It releases the polypeptide chain.

• It dissociates the ribosome from mRNA.

Where does the ribosome bind to the initiator tRNA during translation?

• E site

• A site

• P site

• T site

What happens when a release factor binds during translation?

• The ribosome starts translation.

• The ribosome and polypeptide chain dissociate from mRNA.

• The ribosome moves to the next codon.

• The tRNA transfers an amino acid.

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 is where the tRNA enters the ribosome.

• It is where the tRNA exits the ribosome.

• It is where the amino acids are added to the polypeptide chain.

• It is where the ribosome binds to mRNA.
