Write 12 Conceptual Multiple Choice And Included Answer Key For Each Question For Image Below Translation: Review Copyright O The McGraw-Hill Companies, Inc. Permission required for reproduction or display Translation: mRNA is translated at the ribosome into a polypeptide. Large subunt Initiator tRNA Small subunit 3" Stop codon 5 MRNA Start codon/ 1 Initiation: mRNA, tRNA, and 2 Elongation: The ribosome travels in the 5' to3 direction and synthesizes a polypeptide. 3 Termination: The ribosome reaches a stop codon and all of the components disassemble, releasing a completed polypeptide the ribosomal subunits form a complex.
