Which of the following is NOT a method by which bacteria can be resistant to antibiotics?
Select one:
a. Utilise an alternate pathway of gene expression that is not targeted by the antibiotic.
b. Alter the binding site of the antibiotic, to either prevent it binding, or remove it from the site.
c. Production of enzymes that bind to and break down the specific antibiotic.
d. Production of a cell membrane pump that translocates antibiotics outside the cell.
A potential side effect of antibiotic use is a secondary bacterial or fungal infection, usually associated with regions like the skin, upper-respiratory tract or genitalia. What is the most likely reason for the formation of these secondary infections?
Select one:
a. Antibiotics do not work on viruses, so they are able to establish infections in these locations.
b. Organisms that are antibiotic resistant are usually more virulent, meaning they can survive and cause infection.
c. The antibiotic kills off normal flora, providing an…

a. the origin of transfer
b. the conjugation pilus
c. homologous recombination
d. the relaxosome

g. pillin protein
A transducing particle injects all of the DNA that it contains into a bacterial cell. Which of the following are TRUE? A. The bacterium becomes Hfr B. The bacterium becomes F+ C. The bacterium immediately acquires new functions as the injected DNA is rapidly transcribed and translated into mRNA and proteins D. This injected DNA can integrate into the bacterium’s genome through a process called recombination
