Final answer:
G2 is the phase where the cell prepares for mitosis or cell division. During G2, the cell replenishes its energy stores and synthesizes proteins necessary for chromosome manipulation.
Step-by-step explanation:
G2 can be thought of as the phase where the cell prepares for mitosis, or cell division.
During G2, the cell replenishes its energy stores and synthesizes the proteins necessary for chromosome manipulation. Some cell organelles are duplicated, and the cytoskeleton is dismantled to provide resources for the mitotic spindle. The final preparations for the mitotic phase must be completed before the cell is able to enter the first stage of mitosis.
For example, during G2, microtubules used in the mitotic spindle are manufactured, which are essential for the separation of chromosomes during cell division.
