Cell cycle- mitosis animation

Cell cycle animation
Cell cycle is repeated sequence of events shown by a cell as it grows and divides periodically.
It involves Interphase (growth phase- G1, S , G2) , Karyokinesis (nuclear division)  and Cytokinesis. 
Karyokinesis is of two types: Mitosis and Meiosis
Mitosis - normal cell division process shown by somatic cells.
Meiosis- cell division process shown by sex cells, gameteocytes.

Cell cycle shown in the video explains cell cycle with mitotic division.
