Checkpoint controls in cell division A) are important during G₂ to inhibit the MPF activity and prevent entry into M phase. B) are essential for ensuring the DNA integrity of replication. C) involve the activation of cyclin-dependent kinases by binding to cyclin. D) are points in cell division where specific proteins are phosphorylated. E) All of these statements about checkpoint controls are correct.

Question

Quizplus · Accepted Answer

Checkpoint controls in cell division ensure DNA integrity, involve the activation of cyclin-dependent kinases by cyclins, and include points where specific proteins are phosphorylated to regulate progression through the cell cycle, including the inhibition of MPF activity to prevent premature entry into M phase.
