Question

question 7
proto - oncogenes encode proteins that ___.
a stimulate cell division.
b suppress tumors.
c restrict cell division.
d control programmed cell death.

Explanation:

Proto - oncogenes are normal genes that can become oncogenes due to mutations. They code for proteins that promote cell growth, proliferation, and division. Tumor - suppressor genes, not proto - oncogenes, suppress tumors and restrict cell division. Genes related to apoptosis control programmed cell death.

Answer:

A. stimulate cell division
