PATHOLOGY

Detailed explanation-1: -The M phase is complex and highly regulated. The sequence of events is divided into prophase (including prophase and prometaphase), metaphase, anaphase, and telophase. Mitosis accounts for about 10 percent of the cell cycle (may last only one to two hours) and is much shorter than the interphase.

Detailed explanation-2: -Most cells spend about 90% of their time in interphase. Note that mitosis and meiosis comprise only about 10% of the cell cycle.

Detailed explanation-3: -In anaphase, the shortest stage of mitosis, the sister chromatids break apart, and the chromosomes begin moving to opposite ends of the cell.

Detailed explanation-4: -During interphase, the cell undergoes normal growth processes while also preparing for cell division. It is the longest phase of the cell cycle, cell spends approximately 90% of its time in this phase. In order for a cell to move from interphase into the mitotic phase, many internal and external conditions must be met.
