Solved What happens during M phase mitosis cytokinesis Biology Diagrams Figure 3.2. The stages of mitosis. (Credit) Prophase (the "first phase"): the nuclear envelope starts to dissolve, and the membranous organelles (such as the Golgi apparatus and the endoplasmic reticulum) fragment and disperse toward the periphery of the cell. M phase is the most dramatic period of the cell cycle, involving a major reorganization of virtually all cell components. During mitosis (nuclear division), the chromosomes condense, the nuclear envelope of most cells breaks down, the cytoskeleton reorganizes to form the mitotic spindle, and the chromosomes move to opposite poles. Chromosome segregation is then usually followed by cell M (mitosis) phase: This is the phase in which cell division occurs. Figure 08-01 shows an overview of the stages of the cell cycle. Collectively, we consider G 1, S, and G 2 to be interphase (i.e., the phases "in between" M phase). Figure 08-01: The four stages of the cell cycle.
The M phase of a cell cycle is also called mitosis. This is a form of asexual cell reproduction in eukaryotes, equivalent in most respects to binary fission in prokaryotes. In includes prophase, prometaphase, metaphase, anaphase and telophase, and it relies on the mitotic spindle at each cell pole. The eukaryotic cell cycle consists of four distinct phases: G 1 phase, S phase (synthesis), G 2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm and cell membrane divides forming two daughter cells.

Definition And Phases of Cell Cycle Biology Diagrams
Cytokinesis Cytokinesis, or "cell motion," is the second main stage of the mitotic phase during which cell division is completed via the physical separation of the cytoplasmic components into two daughter cells. Division is not complete until the cell components have been apportioned and completely separated into the two daughter cells. Although the stages of mitosis are similar for most The stages that occur during M phase are summarized in Panel 18-1. The complexity and beauty of M phase, however, are hard to appreciate from written descriptions or from a set of static pictures.
The M phase is the most spectacular phaseโa complex phase of cell cycle in which the replicated genome splits during mitosis, in other words, the nuclear contents are segregated into the daughter cells. The M-Phase, also known as the Mitotic Phase, is a stage in the cell cycle where cell division occurs. It is divided into several stages: Prophase: In this stage, the chromatin condenses into a highly ordered structure called chromosomes. The nuclear envelope breaks down and spindles start to form.
Molecular Biology of the Cell Biology Diagrams
The different phases of a cell cycle include: Interphase - This phase includes the G1 phase, S phase and the G2 phase. M phase - This is the mitotic phase and is divided into prophase, metaphase, anaphase and telophase. Cytokinesis - In this phase the cytoplasm of the cell divides.
