Document Summary
Lecture 18 cell division cycle: following the completion of s phase and transition through g2, the cell undergoes the dramatic upheaval of m phase, this begins with mitosis, during which the sister chromatids are separated and distributed to a pair of identical daughter nuclei, each with its own copy of the genome, mitosis is traditionally divided into give stages prophase, prometaphase, metaphase, anaphase, and telophase, as mitosis is completed, the second major event of m phase cytokinesis divides the cells into two halves, each with an identical nucleus, let us go into detail of each event of m phase. Cytoplasm is divided by a contractile ring of actin and: control of mitosis: myosin, one of the most remarkable features of cell cycle control is that a single protein kinase, m cdk, brings about all of the diverse and complex cell rearrangements that occur in the early stages of mitosis.
