Detailed explanation-1: -G2 Phase (Second Gap) 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-2: -This last stage is all about prepping the cell for mitosis or meiosis. During G2, the cell has to grow some more and produce any molecules it still needs to divide. This includes assembly of the microtubules, which will make up an important structure called the spindle during mitosis.
Detailed explanation-3: -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.
Detailed explanation-4: -The G2 phase continues growth of the cell and prepares the cell for mitosis (M phase) by producing all of the enzymes that the cell will need in order to divide. Color the G2 phase light blue. After the G2 phase of interphase, the cell is ready to start dividing.
