Answer» Phases of Cell cycleHuman cell divides once in approximately 24 hours, which may vary in different organisms. In yeasts it takes about 90 minutes to complete the cell division process.Cell cycle is divided into two basic phases-\tInterphase– it is the phase between two successive M phases. Interphase lasts for 95% of a cell cycle. This phase is called as resting phase but during this period the cells prepare itself for nuclear division by cell growth.\tM Phase– when the actual cell division or mitosis occurs. It starts with karyokinesis (nuclear division) or duplication of chromosome and end with cytokinesis or division of cell matrix (cytoplasm division).The interphase is divided into three further phases:\tG1 phase represents the interval between mitosis and initiation of DNA replication. Cell is continuously active and grows in size.Click on the given link for more:Cell Cycle and Cell Division class 11 Notes Biology ... Right before prophase, the cell spends most of its life in the interphase, where preparations are made before the beginning of mitosis (the DNA is copied). However, since the actual process involves the division of the nucleus, prophase is technically the first stage of this process.The different stages of mitosis occurring during\xa0cell division\xa0are given as follows-InterphaseBefore entering mitosis, a cell spends a period of its growth under interphase. It undergoes the following phases when in interphase:\tG1 Phase:\xa0This is the period before the synthesis of DNA.\tS Phase:\xa0This is the phase during which DNA synthesis takes place.\tG2 Phase:\xa0This is the phase between the end of DNA synthesis and the beginning of prophase. |
