How do quinolones work?
A. Inhibit cell wall synthesis
B. Inhibit protein synthesis
C. Inhibit nucleic acid replication/transcription
D. Injure the plasma membrane
E. Inhibit essential metabolite synthesis
Is it E?

No, sorry. Guess again. //would it help if I gave examples of quinolones?

Yes please. I feel like I know the answer, but I just don't.

Edit: I looked at my notesheet, and I saw I had floroquinolone listed as one of the treatments for Legionnaire's Disease, in conjunction with doxycycline and azithromycin. Knowing that doxycycline and azithromycin are ribosomal inhibitors, I'd change my answer to B.

Yes please. I feel like I know the answer, but I just don't.
Examples include Ciprofloxacin (Ciloxan Ophthalmic and Cipro), Levofloxacin (Levaquin and QUIXIN Ophthalmic), Lomefloxacin (Maxaquin), and Moxifloxacin (Avelox).
this type of antibiotic is bactericidal not bacteriostatic.

Since no one answered, and since the hint given was that the drug is bactericidal, my guess would be D.

The answer was C) inhibition of nucleic acid replication and transcription. They basically inhibit DNA gyrase.
Your turn (I think?)

Just gonna post a new question... hope you guys don't mind... (What's supposed to happen if nobody gets it right?)
What's the difference between resolution and magnification?

What's the difference between resolution and magnification?
Resolution is about separation distance. It is the ability to differentiate between two distinct points that are close to one another. High resolution instruments can differentiate between two close points better than low resolution instruments.

Magnification is just about producing larger images of smaller areas. Instruments with higher magnifications can produce larger images from an area of set size than lower magnification instruments.
Also, in the future, I guess if a question has been inactive for a long period, the bearer should ask another one? I just didn't feel like posing a question after taking three guesses at it, and probably should've made it clearer.
