Question

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?
A. Danio rerio, because they are transparent their first two weeks of life
B. C. elegan, because their neurons are completely mapped
C. S. cerevisiae, because they are minimal model eukaryotes
D. Drosophila, because their DNA genome is well known

Answer 1

Answer:

The correct answer is option A.

Explanation:

Taxol or paclitaxel refers to a chemotherapy drug. It is used in the treatment of various different kinds of cancer. It functions by ceasing the cancer cells from distinguishing into two novel cells, that is, it prevents the growth of cancer.  

In the given case, the model organism, which a researcher can use is Danio rerio or zebrafish as the eggs get developed outside the body of the mother and this organism is suitable for studying as they share 70 percent of the genes with humans. Apart from this, 84 percent of the genes related to human disease exhibit a zebrafish matching part.  

As a vertebrate, the zebrafish possesses the similar prime tissues and organs as humans. Their blood, muscle, eyes, and kidney share various characteristics with the human systems.
