| Eduard Strasburger (1844- 1912) |
In 1884 the famous German botanist, Eduard Strasburger (1844- 1912) coined the terms prophase, metaphase, and anaphase for the different stages of cell division. He used the term metaphase in order to define the stage of nulear division after the chromosomes have divided into chromatids although about 1905 he realized that the chromosomes are already double when nuclear division begins.
Definition
Telophase is a stage of mitosis and meiosis (following anaphase and preceding interphase) of eucaryotic cells in which two daughter nuclei form in the cell and two nuclear envelopes are formed. The cytokinisis (cell separation) usually occurs at the same time.
