In Order for Protein Synthesis to Begin, Which of the Following

question 72

Multiple Choice

In order for protein synthesis to begin, which of the following statements reflects the correct sequence of events?

• A) The AUG codon on mRNA base pairs with the UAC anticodon on tRNA allowing the small and large ribosomal subunits to join the complex.
• B) Translation begins when the ribosome translocates from the A site to the P site on the mRNA
• C) The 5'end of the mRNA binds to the small ribosomal subunit, and the large subunit joins, creating the P and A sites where reactions between codons on the mRNA and anticodons on tRNA are stabilized.
• D) The 3'end of the mRNA binds to the small ribosomal subunit and the AUG anticodon on the tRNA base pairs with the UAC codon on the mRNA, allowing the large ribosomal subunit to attach.
