Detailed explanation-1: -As viewed in the microscope, the cell cycle is divided into two basic parts: mitosis and interphase. Mitosis (nuclear division) is the most dramatic stage of the cell cycle, corresponding to the separation of daughter chromosomes and usually ending with cell division (cytokinesis).

Detailed explanation-2: -In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase.

Detailed explanation-3: -During mitosis, the mitotic spindle directs chromosome segregation. Cytokinesis must only occur between segregated chromosomes to ensure that each daughter cell receives a full set of chromosomes together with a proper complement of cytoplasm and organelles.

Detailed explanation-4: -Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.

Detailed explanation-5: -These phases occur in strict sequential order, and cytokinesis-the process of dividing the cell contents to make two new cells-starts in anaphase or telophase. Stages of mitosis: prophase, metaphase, anaphase, telophase. Cytokinesis typically overlaps with anaphase and/or telophase.
