Question

Quizplus · Accepted Answer

The first step in prokaryotic elongation is the binding of mRNA with the small ribosomal subunit (1). Then, the recognition of the initiation codon occurs (2). The complementary base pairing between the initiator codon and the anticodon of the initiator tRNA happens next (3). After that, the mRNA codon following the initiator codon base pairs with its complementary tRNA (4). Finally, the attachment of the large subunit occurs, and translation can begin (5). Therefore, the correct order is 1, 2, 3, 5, 4, which is option C.
