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.

Mitosis determines the traits presented in the cluster of cells.
It is an hydrophilic substance....<span>Substances that have charge or polarity are </span>hydrophilic<span>, and are likely to dissolve because they have either full or partial charge areas to form hydrogen bonds with water molecules.</span>
A biome is best described as a major type of ecosystem with SYSTEMS OF HABITATS HAVING DIFFERING CLIMATES.
hope this helped!
