A new drug is developed that inhibits formation of the flagellar filament by impairing production of the protein flagellin. Is this going to be a good drug?

#Unit 2. Cellular Organization
  1. Potentially-it would definitely only impair bacteria, but wouldn't matter for the ones that don't use a flagellum to move around.
  2. Potentially-if it could be shown that it also didn't impair the production of the eukaryotic flagellum.
  3. No-our eukaryotic cells depend on flagella to move around in our body, and this would impair that function.
  4. No-bacterial flagella are produced using microtubules, not the protein flagellin. This drug would be useless in eliminating bacteria.
