You are answering a USMLE-style medical question. Question: A laboratory primarily involved with studying cellular proofreading mechanisms is investigating the question of whether the ribosome can recognize a mischarged amino acid and still be incorporated into the growing peptide. In order to do so, they biochemically charge a Lys-tRNA with valine instead of lysine and insert the tRNA into the cell. They design an mRNA sequence that contains only codons for lysine. Which of the following will most likely occur? Options: A) The ribosome will recognize the mischarged tRNA and prevent its incorporation by removing the valine B) The mischarged tRNA with valine will be incorporated in the codons that specificy for lysine C) The mischarged tRNA will be degraded by the proteasome D) The mischarged tRNA will be removed by the lysyl-tRNA synthetase Reply with ONLY the letter of the correct answer (A, B, C, or D). No explanation.
