A scientist introduces a mutation that makes the 60S ribosomal subunit nonfunctional in a human cell line. What would be the predicted effect on translation?
- Translation stalls after the initiation AUG codon is identified.
- The ribosome cannot catalyze the formation of peptide bonds between the tRNAs in the A and P sites.
- The ribosome cannot interact with mRNAs.
- tRNAs cannot exit the E site of the ribosome.
