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.
Which of the following is not made out of RNA? the carriers that shuffle amino acids to a growing polypeptide strand the ribosome the messenger molecule that provides the code for protein synthesis the intron
Figure 15.16 Many antibiotics inhibit bacterial protein synthesis. For example, tetracycline blocks the A site on the bacterial ribosome, and chloramphenicol blocks peptidyl transfer. What specific effect would you expect each of these antibiotics to have on protein synthesis? Tetracycline would directly affect: tRNA binding to the ribosome ribosome assembly growth of the protein chain Chloramphenicol would directly affect tRNA binding to the ribosome ribosome assembly growth of the protein chain
