Chromatin |
A complex body, spherical or rod shaped, that arises from the nuclear network during mitosis, splits longitudinally, and carries a part of the organism's genetic information as genes composed of DNA associated with proteins |
Chromosome |
A localized constriction in a characteristic position on a chromosome, bearing of kinetochore |

What is current methods of dividing stages of mitosis in simple terms? |
Mitosis is artificially divided into four successive stages or phases, although one stage merges into the next without sharp lines of transition |
