How To Use karyokinesis In A Sentence
- All this, it will be noticed, is a case of cell-multiplication, which differs from that which takes place in the unicellular organisms only in its being _invariably_ preceded (as far as we know) by karyokinesis, and in the resulting cells being all confined within a common envelope, and so in not being free to separate. Darwin, and After Darwin (Vol. 1 and 3, of 3) An Exposition of the Darwinian Theory and a Discussion of Post-Darwinian Questions
- Fertilization having been thus effected by fusion of the male and female pronuclei into a single (or new) nucleus, this latter body proceeds to exhibit complicated processes of karyokinesis, which, as before shown, are preliminary to nuclear division in the case of egg-cells. Darwin, and After Darwin (Vol. 1 and 3, of 3) An Exposition of the Darwinian Theory and a Discussion of Post-Darwinian Questions
- Note that macronuclear karyokinesis and cytokinesis has initiated in rad 51 nulls despite the failure to complete micronuclear mitosis.
- Lastly, with respect to karyokinesis, although it is true that the microscope has in comparatively recent years displayed this apparently important distinction between unicellular and multicellular organisms, two considerations have here to be supplied. Darwin, and After Darwin (Vol. 1 and 3, of 3) An Exposition of the Darwinian Theory and a Discussion of Post-Darwinian Questions
- Whether the phenomena of karyokinesis are essentially chemical or not remains to be determined by further investigations.
- As in the case of sexual propagation, so in that of karyokinesis, processes which are common to all the Metazoa are not wholly without their foreshadowings in the Darwin, and After Darwin (Vol. 1 and 3, of 3) An Exposition of the Darwinian Theory and a Discussion of Post-Darwinian Questions
- Here, then (Fig. 29), we see the complex processes of karyokinesis in the first two stages of egg-cell division. Darwin, and After Darwin (Vol. 1 and 3, of 3) An Exposition of the Darwinian Theory and a Discussion of Post-Darwinian Questions
- Indirect division or karyokinesis (karyomitosis) has been observed in all the tissues—generative cells, epithelial tissue, connective tissue, muscular tissue, and nerve tissue. I. Embryology. 1. The Animal Cell
- It is needless to say that I refer to the phenomena of karyokinesis. Darwin, and After Darwin (Vol. 1 and 3, of 3) An Exposition of the Darwinian Theory and a Discussion of Post-Darwinian Questions
- Additionally, cytokinesis blocked cells are thought to be prone to polyploidization if the gap between the daughter nuclei is very small, resulting in incomplete or absent karyokinesis.
