Answer:
grow its cell contents, double its DNA and synthesize proteins
Step-by-step explanation:
Before a cell can carry out mitosis, such cell will need to grow and develop its contents, synthesize (double) DNA, and also synthesize proteins.
Mitosis involves the equational division of non-sex cells to give two daughter cells. Hence, the contents of a cell that wants to divide by mitosis must be enough to be shared by the two daughter cells.
This is why a cell that will divide by mitosis has to go through the G1 phase, the S phase and the G2 phase where the content of the cells grow and develops, DNA of the cell is replicated, and protein is synthesized respectively. All these processes take place during the interpphase stage of the cell cycle.
