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

Identify the correct statement about the ribosomes of prokaryotic and eukaryotic cells. prokaryotic cells always contain only 40s and 60s subunits prokaryotic cells may contain 30s, 40s, 50s, and 60s subunits eukaryotic cells always contain only 40s and 60s subunits eukaryotic cells may contain 30s, 40s, 50s, and 60s subunits eukaryotic cells always contain only 30s and 50s subunits
Why do prokaryotic organisms translate mRNA molecules while being transcribed? Group of answer choices Prokaryotes lack nuclear membranes to separate DNA and mRNA from protein-synthesizing equipment. Prokaryotes use reverse transcriptase to simultaneously translate and transcribe mRNA. Prokaryotes use pre-mRNA to translate, while transcription occurs within the cell. Prokaryotes have functional mRNA that yields portions of the transcribed mRNA into the cytoplasm to allow for translation to occur.
