What are the five phase of a life cycle
inter-phase,pro-phase,meta-phase,anaphase,telophase
Interphase
the period of the cell cycle during which the nucleus is not undergoing division, typically occurring between mitotic or meiotic divisions
Prophase
first and longest phase of mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus
Metaphase
the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindle
Anaphase
the third phase of mitosis, during which the chromosome pairs separate and move toward opposite poles
Telophase
the final stage of mitosis or meiosis, during which a nuclear membrane forms around each set of new chromosomes
The centrioles move toward opposite poles during ___
Prophase
During _____ the nuclear membrane disintegrates
