B) P site
C) A site
D) the large ribosomal subunit

Question

Quizplus · Accepted Answer

The A site in the ribosome represents the location where a codon is being read. The incoming aminoacyl-tRNA binds to the A site and forms a codon-anticodon interaction with the mRNA, allowing for the correct amino acid to be added to the growing polypeptide chain. The P site holds the tRNA carrying the growing polypeptide chain, and the E site is the exit site for tRNA that has already delivered its amino acid. The large ribosomal subunit is responsible for catalyzing peptide bond formation during elongation.
