C) A site
D) the small ribosomal subunit

Question

During elongation, the A site in the ribosome represents the location where a codon is being read. The A site is where the incoming aminoacyl-tRNA binds to the ribosome and pairs with the codon on the mRNA. The P site holds the peptidyl-tRNA, which carries the growing polypeptide chain, while the E site is where the tRNA exits the ribosome after releasing its amino acid. The small ribosomal subunit plays a role in locating the start codon on the mRNA during initiation.
