Checkpoints in the cell cycle are important because they ____
|
|
check for correctly replicated DNA
|
|
|
ensure cells are the correct size and are ready to divide
|
|
|
prevent cells from dividing that could become cancerous

Explanation:
Detailed explanation-1: -Cell cycle checkpoints are surveillance mechanisms that monitor the order, integrity, and fidelity of the major events of the cell cycle. These include growth to the appropriate cell size, the replication and integrity of the chromosomes, and their accurate segregation at mitosis.
Detailed explanation-2: -Checkpoints during cell cycle are important because they ensure the integrity of the cell’s DNA. The process that serves to decrease cellular chromosome number by half is meiosis 1.
Detailed explanation-3: -In the cell cycle, there are three major checkpoints-the G1 checkpoint, the G2 checkpoint, and the spindle checkpoint.
