title: Cell cycle text: a series of changes that takes place in a newly formed cell and its nucleus, before it becomes capable of division again. It is also called preparatory phase or intermitosis. Previously it was called resting stage because there is no apparent activity related to cell division.Typically interphase lasts for at least 91% of the total time required for the cell cycle. Interphase proceeds in three stages, G, S, and G, followed by the cycle of mitosis and cytokinesis. The cell's nuclear DNA contents are duplicated during S phase but may continue till G in case of heterochromatin. The first phase title: Cell cycle text: cell cycle and enter S phase (2) Stop cell cycle and enter G phase for undergoing differentiation. (3) Get arrested in G phase hence it may enter G phase or re-enter cell cycle. The deciding factor is availability of Nitrogens and storage of energy rich compounds at the deciding point called check point (Restriction point). This check point is called the restriction point or START and is regulated by G/S cyclins, which cause transition from G to S phase. Passage through the G check point commits the cell to division. The ensuing S phase starts when DNA synthesis commences; when title: Cell cycle text: cells. In cells with a nucleus, as in eukaryotes, the cell cycle is also divided into three periods: interphase, the mitotic (M) phase, and cytokinesis. During interphase, the cell grows, accumulating nutrients needed for mitosis, preparing it for cell division and duplicating its DNA. During the mitotic phase, the chromosomes separate. During the final stage, cytokinesis, the chromosomes and cytoplasm separate into two new daughter cells. To ensure the proper division of the cell, there are control mechanisms known as cell cycle checkpoints. The cell-division cycle is a vital process by which a single-celled fertilized egg develops into a mature title: Cell cycle text: within interphase, from the end of the previous M phase until the beginning of DNA synthesis, is called G (G indicating "gap"). It is also called the growth phase. During this phase, the biosynthetic activities of the cell, which are considerably slowed down during M phase, resume at a high rate. The duration of G is highly variable, even among different cells of the same species. In this phase, the cell increases its supply of proteins, increases the number of organelles (such as mitochondria, ribosomes), and grows in size. In G phase, a cell has three options. (1) To continue title: Cell cycle text: the cell for initiation of cell division. G is a resting phase where the cell has left the cycle and has stopped dividing. The cell cycle starts with this phase. The word "post-mitotic" is sometimes used to refer to both quiescent and senescent cells. Non-proliferative (non-dividing) cells in multicellular eukaryotes generally enter the quiescent G state from G and may remain quiescent for long periods of time, possibly indefinitely (as is often the case for neurons). This is very common for cells that are fully differentiated. Cellular senescence occurs in response to DNA damage and external stress and usually constitutes
