Question

a mutation causes a cell to ignore cyclin signals and bypass checkpoints. what is the most likely result? the cell will enter apoptosis immediately the cell will repair itself quickly the cell will stop in the g_ phase the cell will divide uncontrollably

Explanation:

Cyclins regulate the cell cycle. Checkpoints ensure proper cell - cycle progression. If a cell ignores cyclin signals and bypasses checkpoints, it loses control over the cell - cycle. Apoptosis (programmed cell death) is triggered by normal mechanisms when something is wrong, but if the cell ignores signals, it won't enter apoptosis. Repair mechanisms also rely on checkpoint signals. Stopping in the \(G_0\) phase (quiescent phase) is a regulated process. Uncontrolled division occurs when the regulatory mechanisms (cyclin signals and checkpoints) are bypassed.

Answer:

The cell will divide uncontrollably
