A site (Aminoacyl site)
D
R site (Ribosomal site)
Verified step by step guidance1
Understand the role of tRNA in translation: tRNA molecules are responsible for bringing amino acids to the ribosome during protein synthesis.
Learn about the ribosome structure: The ribosome has three main sites for tRNA binding - the A site (Aminoacyl site), the P site (Peptidyl site), and the E site (Exit site).
Identify the function of each site: The A site is where the tRNA carrying the next amino acid binds, the P site holds the tRNA with the growing polypeptide chain, and the E site is where the uncharged tRNA exits the ribosome.
Determine the location of uncharged tRNA: After the tRNA has transferred its amino acid to the growing polypeptide chain, it becomes uncharged and moves to the E site.
Conclude that the uncharged tRNA is found in the E site (Exit site) of the ribosome during translation.
