The cell cycle consists of an alternation between mitotic (M) phase which appears as a period of dramatic activity under the microscope, and a preparative period called interphase which consists of three phases called G1, S, and G2.    

Interphase- the cell growth and coping of its DNA
Mitotic (M) phase- the separation of DNA and division of the cytoplasm-formation of two new cells.

Ithink the dna sequences may vary but the amino acid sequences are identical.
