Question

what is one potential consequence of uncontrolled cell division?
formation of tumors
activation of tumor suppressor genes
inhibition of oncogene expression
increased dna repair mechanisms

Explanation:

Uncontrolled cell division leads to abnormal cell growth. Tumor suppressor genes inhibit cell division; their activation would not cause uncontrolled division. Oncogenes promote cell division; inhibiting their expression would not lead to uncontrolled division. Increased DNA repair mechanisms fix errors and do not cause uncontrolled division. Tumors are formed by uncontrolled cell growth.

Answer:

formation of tumors
