The process through which cells multiply and divide into two new cells is known as the cell cycle.
Mitotic phase:
The mitotic phase or M. phase is one of the phases of the cell cycle.
Mitosis is that step in the cell cycle where the newly formed DNA is separated and two new cells are formed with the same number and kind of chromosomes as the parent nucleus
Prophase, metaphase, anaphase, and telophase are the stages of mitosis.
Telophase is the end of mitosis as at this phase nuclear membrane reappears and chromosomes decondensed.
Final answer: Telophase marks the end of the Mitotic or M. phase.
