Part 1: Study of mitosis
Background Mitosis is a cell division in which the two daughter cells receive the same
Information number of chromosomes as are present in the parent cell. It is a continuous
process in which sequence of events is divided into two major phases:
karyokinesis (division of nucleus) and cytokinesis (division of cytoplasm).
Karyokinesis is divided into four phases i.e. prophase, metaphase, anaphase
and telophase.
Interphase Prophase Prophase Metaphase
Anaphase Anaphse Telophase Interphase
