If a growth factor receptor mutation constitutively activates cell division signaling in intestinal crypt stem cells, which consequence is most likely?

A)Enhanced DNA repair mechanisms activate
B)Uncontrolled proliferation overwhelms apoptosis
C)Increased differentiation reverses phenotype
D)Metabolic quiescence arrests cell growth

💡 Explanation

When growth factor receptors are constitutively active, it leads to continuous cell division signaling, overwhelming normal apoptotic pathways; because the checkpoints are bypassed, uncontrolled proliferation occurs. Therefore, the balance tips toward cell survival rather than programmed cell death, rather than quiescence or differentiation.
