1. How does penicillin act on a bacterial cell - or stated another way - what is the mechanism of action of penicillin? what is the cellular target of the antibiotic?

2. Why does penicillin not act on human cells? or stated another way - why does penicillin have selective toxicity?

3. Be specific about why the penicillin may be able to act differently on one type of cell. What about that one type of cell allows penicillin to act more effectively?

Bacterial transformation allows a gene from another organism to be put into a bacterial cell. This would allow the bacterial cell to produce the protein that the gene codes for. Several steps are needed to transform bacteria; put the following steps in the correct order. 1. Add a bacterial promoter and terminator, and add sequences that will be cut by a specific restriction enzyme to the ends of the DNA piece. 2.Cut the cDNA and plasmid with the same restriction...
