Question

1. why are checkpoints important in the cell cycle?

Explanation:

Checkpoints in the cell cycle are crucial as they act as regulatory mechanisms. They ensure that the cell has completed necessary processes like DNA - replication accurately before proceeding to the next phase. They prevent the propagation of damaged or incomplete genetic material, maintaining genomic stability and proper cell function.

Answer:

Checkpoints in the cell cycle are important because they ensure proper cell division by verifying that essential processes such as DNA replication are completed correctly and that there is no damage to the genetic material, thus maintaining genomic integrity and normal cell function.
