Which of the Following Statements Does NOT Describe the Events

question 7

Multiple Choice

Which of the following statements does NOT describe the events in prokaryotic translation elongation?

• A) The nucleotides in the Shine-Dalgarno sequence of the mRNA pair with their complementary nucleotides in the 16S rRNA.
• B) A ribosome with a growing peptide attached to a tRNA in the P site accepts a charged tRNA with the next amino acid into the A site. The charged tRNA enters as a complex with EF-Tu and GTP.
• C) If the anticodon of the charged tRNA matches the codon, GTP is cleaved and EF-Tu exits and is regenerated to EF-Tu-GTP by EF-Ts.
• D) A peptide bond is formed by the peptidyl transferase activity of the large subunit rRNA. The polypeptide chain on the tRNA in the P site is transferred to the amino acid on the tRNA in the A site.
• E) The ribosome translocates toward the 3' end of the mRNA with the aid of EF-G and GTP hydrolysis. The empty tRNA that was in the P site moves to the E site and exits. The tRNA with the polypeptide that was in the A site moves to the P site.
