Which step occurs in the E site of the ribosome during translation?

Verified step by step guidance

Understand the role of the ribosome in translation: The ribosome is the molecular machine that facilitates the synthesis of proteins by translating mRNA into a polypeptide chain.
Identify the three sites of the ribosome: The ribosome has three key sites known as the A (aminoacyl), P (peptidyl), and E (exit) sites, each playing a distinct role during translation.
Clarify the function of the E site: The E site, or exit site, is where the tRNA, after having transferred its amino acid to the growing polypeptide chain, exits the ribosome.
Differentiate the steps of translation: Recognize that the tRNA brings a new amino acid to the A site, the peptide bond formation occurs at the P site, and the tRNA exits from the E site.
Conclude with the correct step for the E site: The correct step that occurs in the E site of the ribosome during translation is that the tRNA exits the ribosome.
