How has the study of mitosis affected scientists’ knowledge of cancer?
a.it led to a study of how to induce cancer cells to divide more rapidly.
b.it led to an understanding of how cancer cells divide so rapidly.
c.it led to the development of contact-inhibition regulators.
d.it led to the discovery of how to prevent cancer cells from dividing.

The correct answer is option C. it led to the development of the contact-inhibition regulators.

Explanation:

Mitosis is a cell division that produces two identical daughter cells with exact chromosome numbers as the parent cell. Cancer cells are the products of the mitosis due to the failing of inhibitors.

The study of mitosis helped scientists to discover and develop the contact inhibitor regulators which help in cells to stop dividing further.

Thus, the correct answer is an option - C. it led to the development of contact-inhibition regulators.
