Detailed explanation-1: -Interphase is not a phase of mitosis. It is a phase prior to mitosis during which the cell does not divide but makes preparations to divide.
Detailed explanation-2: -Interphase is often included in discussions of mitosis, but interphase is technically not part of mitosis, but rather encompasses stages G1, S, and G2 of the cell cycle. The cell is engaged in metabolic activity and performing its prepare for mitosis (the next four phases that lead up to and include nuclear division).
Detailed explanation-3: -No, interphase is not part of mitosis, although both are part of the larger cell cycle. Interphase is the cell division phase that occurs before mitosis. During interphase, the cell gets itself ready for mitosis. The mitosis phase is marked by the division of the nucleus.
Detailed explanation-4: -Interphase includes G1, S, and G2 phases. Mitosis and cytokinesis, however, are separate from interphase.
Detailed explanation-5: -In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase. Before entering meiosis I, a cell must first go through interphase. This is the same interphase that occurs before mitosis.
