The correct answer is: c) The catalytic site for peptide bond formation is formed primarily from an rRNA
Ribosomal ribonucleic acid (rRNA) together with proteins is the major component of the ribosome. rRNA is essential for protein synthesis in all living organisms. Ribosomes contain two major rRNAs (and abot 50 proteins) that form two ribosomal subunits, the large one and the small one. The large subunit rRNA has a function of ribozyme: catalyzes peptide bond formation.
