The following points highlight the two main steps of mitosis. The steps are: 1. Karyokinesis 2. Cytokinesis. Step # 1. Karyokinesis: Karyokinesis (Gk. karyon- nucleus, kinesis- movement) is also called indirect nuclear division because the nucleus passes through a complicated sequence of events before forming two daughter nuclei. Though the process is continuous one without any pauses, it has been [...]
In this article we will discuss about Mitosis which is an indirect type of cell division:- 1. Subject-Matter of Mitosis 2. Process of Mitosis 3. Significance. Subject-Matter of Mitosis: Walter Fleming (1878), a German biologist, was the first to study the cell division. He stated that the nucleus of a dividing cell undergoes a series of changes. To this [...]
In this article we will discuss about the similarities and dissimilarities between mitosis and meiosis. Similarities between Mitosis and Meiosis: Mitosis: 1. Mitosis Involves nuclear division 2. Mitosis Involves spindle apparatus 3. Mitosis is Genetically controlled 4. Mitosis has various successive phases 5. Mitosis Involves cytokinesis at the end. Meiosis: 1. Meiosis also involves nuclear division 2. Meiosis also involves [...]
