amitotic उदाहरण वाक्य
उदाहरण वाक्य
अधिक: आगे- :I've changed amitotic to post-mitotic.
- These structures can divide symmetrically by an amitotic nuclear fission process, forming new " bells ".
- This amitotic process causes the two daughter cells to potentially have identical germ-line nucleus but a different somatic nucleus in regards to the copy numbers of the chromosomes.
- As the somatic nucleus is the nucleus that is transcriptionally active, this somatic copy number mutation derived by the amitotic process could have fitness consequences for the individual cell.
- Sorry, didn't read our article properly, and thought amitotic was supposed to refer to glia cels, which talk 17 : 47, 27 December 2007 ( UTC)
- Chen and Wan ( 1986 ) not only reported amitosis in rat liver, but also presented a mechanism for a four-stage amitotic process whereby chromatin threads are reproduced and equally distributed to daughter cells as the nucleus splits in two.
- Asymmetric cell division has also been described in polyploid giant cancer cells and low eukaryotic cells and reported to occur by the amitotic processes of splitting, budding, or burst-like mechanisms ( Zhang, Wang, and Zhang; 2012 ).
- Isakova GK, Shilova IE . 2003 . [ Frequency ratio of two forms of amitotic division of trophoblast cell nuclei in the mink blastocysts during the period of delayed implantation ] . [ Article in Russian ] Izv Akad Nauk Ser Biol . ( 4 ) : 395-8.
- For instance, naturally occurring polyploid placental cells have been shown capable of producing nuclei with diploid or near-diploid complements of DNA . Furthermore, Zybina and her colleagues have demonstrated that such nuclei, derived from polyploid placental cells, receive one or two copies of a microscopically identifiable region of the chromatin, demonstrating that even without the reassuring iconography of identical chromosomes being distributed into " identical " daughter cells, this particular amitotic process results in representative transmission of chromatin.
- A review of the resulting literature not only affirms the involvement of amitosis in cell proliferation, it also explores the existence of more than one amitotic mechanism capable of producing " progeny nuclei " without the involvement of " mitotic chromosomes . " One form of amitosis involves fissioning, a nucleus splitting in two without the involvement of chromosomes, and has been reported in placental tissue as well as in cells grown from that tissue in rats ( Ferguson and Palm, 1976 ), in human trophoblasts ( Cotte et al ., 1980 ), and in mouse trophoblasts ( Kuhn, Therman and Susman, 1991 ).
