![]() It begins precipitously with the synchronous splitting of each chromosome into its sister chromatids called daughter chromosomes with one kinetochore.Centromeres occupy the plane of the equator of the mitotic apparatus (equatorial or metaphasic plate).Chromosomes are the shortest and thickest.Microtubules attach to the kinetochore balanced bipolar force holds the chromosomes on the metaphasic plate.The spindle appears to be aligning the chromosomes at the metaphase plate is the characteristic feature of the stage.The nuclear envelope’s disappearance marks the prometaphase’s initiation and enables the mitotic spindle to interact with the chromosome. ![]() Formation of the spindle or mitotic apparatus in the cytoplasm takes place.The cell begins the process of division. ![]() The appearance of a thin-thread-like condensing chromosome containing two chromatids held together by the centromere marks the first phase of mitosis, called prophase.Prophase (Pro= Before Phasis= Appearance) This phase initiates at the point of interphase (G2 phase). It is the short period of chromosome condensation, separation, and cytoplasmic division. Continuous synthesis of RNA and proteins that is required for cell growth takes place.The phase where DNA synthesis ends and the prophase stage initiates.Also known as the second gap or growth phase, or resting phase of interphase.It involves the synthesis of histone protein (needed for replication), and two DNA molecules are formed by replication.Also known as S-phase or synthetic phase.It involves the synthesis of RNA, protein, and membranes needed for the development of cytoplasm and nucleus of daughter cells.This phase is also known as the resting phase, first gap phase, or first growth phase.It is the prolonged cell cycle phase where the daughter cell prepares before the mitosis phase begins. G1 phase, S phase, and G2 phase are combined in the interphase. Howard and Pele (1953) have divided the cell cycle into G1, S, G2, and M phases. Stages of Mitosis Cell Division Stages of Mitosis Cell Division Meiotic I has four stages: prophase I, metaphase I, anaphase I, and telophase I without cytokinesis. Meiotic II follows meiotic I without intervening interphase. The karyokinesis of meiosis cell division has two meiotic divisions: meiotic I and meiotic II. The M phase is where cell division begins and has four steps: prophase, metaphase, anaphase, and telophase. The karyokinesis stage of mitosis has two primary phases: interphase and M phase. The general steps of cell division are karyokinesis (a division of the nucleus) and cytokinesis (a division of cytoplasm). In contrast, meiosis does not produce identical daughter cells and occurs in reproductive cells. Mitosis cell division is the process cells use to make exact replicas of themselves, so it occurs in somatic or non-reproductive cells. The cell division in eukaryotic organisms is usually of two types: mitosis and meiosis. ![]() Cell division is when the parent cell multiplies into two or more daughter cells. The wounds in your body, the healing of the broken parts of plants, and the repairing of different damaged parts of animals occur due to the cell’s ability to divide.
