1.
Figure 15.11 A scientist splices a eukaryotic promoter in front of a bacterial gene and inserts the gene in a bacterial chromosome. Would you expect the bacteria to transcribe the gene?
2.
Figure 15.13 Errors in splicing are implicated in cancers and other human diseases. What kinds of mutations might lead to splicing errors? Think of different possible outcomes if splicing errors occur.

Figure 15.18 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
