The two types of cell cycle genes that, if mutated, cause cancer cells to divide uncontrollably are called tumor suppressor genes and

Agrowth factors.
Bproto-oncogenes.
Ccancer genes.
Dtelomeres.

Verified Answer :

Tumor suppressor genes and proto-oncogenes cause cancer cells to divide uncontrollably.

The answer is B) proto-oncogenes.

Answer:

The correct answer is option B. "proto-oncogenes".

Explanation:

Tumor suppressor genes and proto-oncogenes are two types of genes that can cause the development of cancer cells if they suffer a mutation. The main difference between tumor suppressor genes and proto-oncogenes is the way they cause cancer. If tumor suppressor genes are inactivated they produce cancer cells, while if proto-oncogenes are activated is when they produce cancer cells.
