Question

There are three checkpoints in the cell cycle what is the role.

Answer 1

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.

Cell cycle checkpoints

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.
