Detailed explanation-1: -If errors or damage are detected, the cell will pause at the G 2start subscript, 2, end subscript checkpoint to allow for repairs. If the checkpoint mechanisms detect problems with the DNA, the cell cycle is halted, and the cell attempts to either complete DNA replication or repair the damaged DNA.
Detailed explanation-2: -The G2 checkpoint prevents cells from entering mitosis when DNA is damaged, providing an opportunity for repair and stopping the proliferation of damaged cells. Because the G2 checkpoint helps to maintain genomic stability, it is an important focus in understanding the molecular causes of cancer.
Detailed explanation-3: -The cells possessing a defective G2-M checkpoint to enter the M phase prior to DNA being repaired, it generally leads to death post the cell division or apoptosis.
Detailed explanation-4: -So, what happens in G2 of the cell cycle? The second growth phase starts to prepare the cells with newly replicated DNA for entry into the mitosis phase by putting in place the necessary organelles for mitosis.
