Which of the following statements is true about the small ribosomal subunit?
A) It catalyzes peptide bond synthesis.
B) It is responsible for proofreading of the amino acid incorporated in response to a given codon.
C) It forms a complex with initiator tRNA and mRNA
D) It contains both A and P sites for tRNA attachment.
E) none is true

Question

Quizplus · Accepted Answer

The small ribosomal subunit forms a complex with the initiator tRNA and mRNA to initiate translation. A is incorrect because peptide bond synthesis is catalyzed by the large ribosomal subunit. B is incorrect because proofreading is carried out by aminoacyl-tRNA synthetases. D is incorrect because the A and P sites are found on the large ribosomal subunit.
