← Life Sciences & MedicineAn intestinal epithelial cell activates the KRAS oncogene due to a mutation. Which outcome is most likely?
A)Reduced cell cycle arrest signaling
B)Decreased rate of cellular apoptosis
C)Uncontrolled cellular proliferation begins✓
D)Increased DNA damage repair rate
💡 Explanation
Activation of the KRAS oncogene drives uncontrolled cell growth, because it disrupts normal regulatory signals and promotes continuous cell division through the MAPK pathway. Therefore, the most likely outcome is uncontrolled cellular proliferation, rather than cell cycle arrest or decreased apoptosis.
