Question

Quizplus · Accepted Answer

The cell cycle is primarily regulated through a series of checkpoints. These checkpoints ensure that the cell only progresses to the next stage of the cycle if certain conditions are met, such as the proper replication of DNA and the correct alignment of chromosomes. This system prevents errors in cell division that could lead to problems like cancer.
