Mitosis (ib theem hauv lub voj voog ntawm tes) tshwm sim Tom qab DNA nyob rau hauv ib lub cell tau duplicated, txhais tau tias muaj ob pawg ntawm chromosomes nyob rau hauv ib lub cell. Qhov tshwm sim ntawm mitosis tsis muaj cytokinesis yuav ua ib lub cell uas muaj ntau tshaj ib lub nucleus. Xws li ib tug cell hu ua multinucleated cell. Qhov no ua tau ua ib tug txheej txheem.

Hauv qhov no, mitosis puas tuaj yeem tshwm sim thaum tsis muaj cytokinesis?

Mitosis tuaj yeem tshwm sim thaum tsis muaj cytokinesis vim cytokinesis tshwm sim tom qab mob mitosis . Xwb, txij li thaum cytokinesis tsis yog tshwm sim , cov nucleus yuav txuas ntxiv faib thiab dhau los ua ib lub cell loj. Daim duab hauv qab no qhia txog kev faib cell hauv tib neeg testis. Cov noob qes yog gametes.

Tom qab ntawd, lo lus nug yog, hom cell twg tsis raug cytokinesis? Cov cell Lub voj voog culminates hauv kev faib ntawm cytoplasm los ntawm cytokinesis . Hauv ib txwm cell , cytokinesis nrog txhua mob mitosis , txawm tias ib txhia hlwb , xws li Drosophila embryos (sib tham tom qab) thiab vertebrate osteoclasts (sib tham hauv Tshooj 22), raug mitosis tsis muaj cytokinesis thiab ua multinucleate.

Puas yog mitosis thiab cytokinesis xav tau rau kev yug me nyuam asexual?

Mitosis tsim cov nuclei tshiab nrog tib yam chromosomal endowment raws li niam txiv nucleus. C) Mitosis thiab cytokinesis yog xav tau rau kev yug me nyuam asexual.

Ib qho piv txwv ntawm cytokinesis yog dab tsi?

ib qho ntawm ntau yam tshuaj, xws li interferon, interleukin, thiab kev loj hlob yam tseem ceeb, uas tau zais los ntawm qee lub hlwb ntawm lub cev tiv thaiv kab mob thiab muaj kev cuam tshuam rau lwm lub hlwb.
