Question

Positive cell cycle regulators may become mutated to ________.

1) tumor suppressor genes
2) oncogenes
3) proto-oncogenes

Answer 1

Positive cell cycle regulators that become mutated to oncogenes are called proto-oncogenes. These mutations can disrupt the regulation of the cell cycle and lead to uncontrolled cell division.

Step-by-step explanation:

The positive cell cycle regulators that can become mutated to oncogenes are called proto-oncogenes. Proto-oncogenes are normal genes that, when mutated, can cause a cell to become cancerous. These mutations usually result in a less functional or non-functional protein, which can disrupt the regulation of the cell cycle and lead to uncontrolled cell division.
