A cell has damaged DNA. The G2 checkpoint is responsible for checking this abnormality during the cell cycle.
There are three major checkpoints that can be seen in the cell cycle. They are G1/S checkpoints, G2/M checkpoints, and the spindle assembly checkpoints (SAC).
The G2 checkpoint is responsible for checking the accurate replication of all chromosomes that have already been replicated. It also ensures that the replicated DNA is not damaged before the cell enters mitosis.
The G1 checkpoint prevents cells from replicating damaged forms of DNA and forces the cell to remain in the resting state.
Cell cycle checkpoints significantly regulate and control the overall mechanism of the cell cycle in eukaryotic organisms. They also ensure the accurate and valid progression of the cell cycle in each step of it.
Therefore, a cell has damaged DNA. The G2 checkpoint is responsible for checking this abnormality during the cell cycle.
