PATHOLOGY

Detailed explanation-1: -The G2 phase is the second gap phase in the growing and preparatory period of a cell’s life. It helps and checks cell activities before cell division in the mitosis phase can begin. The growth period of the cell cycle or interphase is spread over three phases, G1, S, and G2.

Detailed explanation-2: -In the G2 phase, the cell replenishes its energy stores and synthesizes proteins necessary for chromosome manipulation. Some cell organelles are duplicated, and the cytoskeleton is dismantled to provide resources for the mitotic phase. There may be additional cell growth during G2.

Detailed explanation-3: -Cell cycle checkpoints provide the cell time to complete replication and repair the DNA damage before it can continue to the next cell cycle phase. The G2/M checkpoint plays an especially important role in ensuring the propagation of error-free copies of the genome to each daughter cell.

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. The cell cycle is a vital part of the continued persistence of all eukaryotes and prokaryotes.
