During elongation, the codon being read is located in the A site of the ribosome, where the incoming aminoacyl-tRNA matches its anticodon with the codon on the mRNA. The P site holds the tRNA with the growing polypeptide chain, and the E site is where the spent tRNA exits the ribosome. The small subunit is involved in the initial binding of mRNA and the scanning for the start codon.
