Kinesis example sentences

Skoog and Miller, later identified and crystallised the cytokinesis promoting active substance that they termed kinetin.The M Phase starts with the nuclear division, corresponding to the separation of daughter chromosomes (karyokinesis) and usually ends with division of cytoplasm (cytokinesis).Plant cells however, are enclosed by a relatively inextensible cell wall, thererfore they undergo cytokinesis by a different mechanism.Interkinesis is followed by prophase , a much simpler prophase than prophase I.By the end of diakinesis, the nucleolus disappears and the nuclear envelope also breaks down.The nuclear membrane and nucleolus reappear, cytokinesis follows and this is called as diad of cells (Figureure 3).Cytokinins have specific effects on cytokinesis, and were discovered as kinetin (a modified form of adenine, a purine) from the autoclaved herring sperm DNA.These are leptotene, zygotene, pachytene, diplotene and diakinesis.Mitosis accomplishes not only the segregation of duplicated chromosomes into daughter nuclei (karyokinesis), but the cell itself is divided into two daughter cells by a separate process called cytokinesis at the end of which cell division is complete (Figureure 2 e).Nuclear division is then followed by the cytoplasmic division and is called cytokinesis.It has been further subdivided into the following five phases based on chromosomal behaviour, i.e., Leptotene, Zygotene, Pachytene, Diplotene and Diakinesis.In some organisms karyokinesis is not followed by cytokinesis as a result of which multinucleate condition arises leading to the formation of syncytium.Meiosis is initiated immediately after cytokinesis, usually before the chromosomes have fully elongated.Meiosis ends with telophase , in which the two groups of chromosomes once again get enclosed by a nuclear envelope; cytokinesis follows resulting in the formation of tetrad of cells i.e., four haploid daughter cells.The final stage of meiotic prophase I is diakinesis.
