This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Molecular Genetics, Subject name: Biochemistry
Which of the following functionally componetent of largest unit of the ribosomes 
Select and explain. 
A. tRNA, B. mRNA, C. Catalyze formation of the peptides, D. Formation of the polyribosomes
C: Catalyze formation of the peptides
Answer: C: Catalyze formation of the peptides 
Explanation: (Catalyzes formation of the peptides) (436 - Lippincott's 4th)Polyribosome {Polysome) is used when several ribosomes simultaneously translate on a singe mRNA* The large ribosomal subunit catalyzes formation of the peptide bonds that link amino acids residues in a protein.* The small subunit binds mRNA and is responsible for the accuracy of translation by ensuring correct base- pairing between the codon in the m RNA and the anticodon of the tRNA
