Taxol is a common drug used in cancer treatments that acts as a microtubule stabilizer to inhibit cell division. If a researcher wanted to see how this drug affects development, which model organism would they use and why?

Danio rerio or Zebrafish

Explanation:

Taxol is considered an anticancer drug which can inhibit cancer by interfering with the machinery of cell division. The drug is obtained from the bark of Taxus baccata.

The taxol interferes with the formation of the mitotic spindle by inhibiting the process of microtubule formation or causes depolymerisation.

The model organism that should be selected to observed the mechanism of taxol would be a transparent organism which can easily allow the passing light.

That transparent model organism used by the biologist is Zebrafish as the zebrafish at its embryonic stage is transparent and the mutant produced which lacks the pigments of the zebrafish.

Thus, Zebrafish is the correct answer.
