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.
The centrally constricted region that forms across the central axis of a cell during cytokinesis, constricted by the closing of the contractile ring until the daughter cells are finally separated, [2] but occasionally persisting as a tether between the two cells for as long as a complete cell cycle.

In eukaryotes, the cell cycle consists of four main stages: G 1, during which a cell is metabolically active and continuously grows; S phase, during which DNA replication takes place; G 2, during which cell growth continues and the cell synthesizes various proteins in preparation for division; and the M phase, during which the duplicated ...
A cell during anaphase. Microtubules are visible in green. Stages of late M phase in a vertebrate cell. Anaphase (from Ancient Greek ἀνα-() 'back, backward' and φάσις (phásis) 'appearance') is the stage of mitosis after the process of metaphase, when replicated chromosomes are split and the newly-copied chromosomes (daughter chromatids) are moved to opposite poles of the cell.
Three types of cell division: binary fission (taking place in prokaryotes), mitosis and meiosis (taking place in eukaryotes).. When cells are ready to divide, because cell size is big enough or because they receive the appropriate stimulus, [20] they activate the mechanism to enter into the cell cycle, and they duplicate most organelles during S (synthesis) phase, including their centrosome.
The cell cycle is the cycle of events in a cell from one cell division to the next. Subcategories. This category has the following 5 subcategories, out of 5 total. ...
An illustration of the stages of mitosis in a human cell from Gray's Anatomy. Cell cycle – The series of events that take place in a eukaryotic cell leading to its replication. Interphase – The stages of the cell cycle that prepare the cell for division. Mitosis – In eukaryotes, the process of division of the nucleus and genetic material.
cell cycle The ordered series of events which take place in a cell leading to duplication of its genetic material and ultimately the division of the cytoplasm and organelles to produce two or more daughter cells. These events can be broadly divided into phases of growth and division, each of which can vary in duration and complexity depending ...
