Question

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

Answer 1

It led to an understanding of how cancer cells divide so rapidly.

Explanation: studying mitosis and the cell cycle uncovered the molecular controls (checkpoints, cyclins/CDKs, oncogenes, tumor suppressors, loss of contact inhibition) that explain why cancer cells proliferate uncontrollably.
