Identify some of the things needed to be checked before to cell moves through the stages of mitosis.

The things needed to be checked before the cell moves through the stages of mitosis are 1 DNA of cell undergoing mitosis 2 chromosome number of the cell moving through the stages of mitosis,3 Amount of RNA and protein present in the cell undergoing division.

Explanation:

DNA of the cell undergoing mitosis

It is very important thing to note that cell cycle regulatory mechanism should check that the cell undergoing mitosis should have normal DNA.Cells with damaged DNA are restricted to enter mitotic phase.

Chromosome number of the cell

The most thing of the interphase regulation to  check that DNA has replicated once per cycle .This is very very important thing to maintain normal chromosome number of the cell entering mitosis.

Amount of RNA and proteins synthesized

The G1 and G2 phase of the cell cycle helps in the synthesis of RNA and protein molecules.Significant amount  proteins should be present in the cell undergoing mitosis.
