Detailed explanation-1: -M phase. During the mitotic (M) phase, the cell divides its copied DNA and cytoplasm to make two new cells. M phase involves two distinct division-related processes: mitosis and cytokinesis.

Detailed explanation-2: -At the molecular level, however, interphase is the time during which both cell growth and DNA replication occur in an orderly manner in preparation for cell division. The cell grows at a steady rate throughout interphase, with most dividing cells doubling in size between one mitosis and the next.

Detailed explanation-3: -Kinetin or cytokinin increase the rate of mitosis by reducing the duration of Interphase.

Detailed explanation-4: -Mitosis is conventionally divided into five stages known as prophase, prometaphase, metaphase, anaphase, and telophase. While mitosis is taking place, there is no cell growth and all of the cellular energy is focused on cell division.

Detailed explanation-5: -G2 phase (growth) G2 phase occurs after DNA replication and is a period of protein synthesis and rapid cell growth to prepare the cell for mitosis. During this phase microtubules begin to reorganize to form a spindle (preprophase).
