There are three checkpoints in the cell cycle what is the role.
Tanzania [10]

The 3 checkpoints include G1 where the cell growth is checked, G2 where the integrity of the DNA/chromosome is checked, and M where the integrity of the metaphase plate is checked.

<h3>Cell cycle checkpoints</h3>

There are 3 regulatory checkpoints in the life cycle of cells:

  • G1: the size of the cell, the presence of growth factors, and the integrity of the DNA are checked before the cell irreversibly commits to division.
  • G2: the integrity of the DNA and the correctness of the replication process at the S-phase are checked.
  • M: correct attachment of the spindle fibers to the chromosomes at the metaphase plate is checked.

More on cell cycle checkpoints can be found here: brainly.com/question/2128300
