Which of the following statement about the ribosome complex is correct?

A. Small subunit binds an mRNA and large subunit joint with the mRNA/small subunit complex to form a complete ribosome

B. The large ribosomal subunit has a P site (peptidyl site) that holds the growing polypeptide chain and an A site (aminoacyl site) that binds the next amino acid to be added to the growing polypeptide chain

C. The additon of new amino acid in the A site to the growing polypeptide chain is catalyzed by one of the enzymes that form the large ribosomal subunit

D. All of the above

Answer: Option D
