Mitosis yog txheej txheem ntawm kev faib tawm nuclear hauv eukaryotic hlwb uas tshwm sim thaum niam txiv cell faib los tsim ob lub hlwb zoo tib yam . Mitosis yog conventionally muab faib ua tsib theem hu ua prophase, prometaphase prometaphase Prometaphase yog theem thib ob ntawm mitosis, txheej txheem uas cais cov noob caj noob ces duplicated nqa nyob rau hauv lub nucleus ntawm niam txiv cell ua ob zoo tib yam. cov ntxhais. Thaum lub sij hawm prometaphase, lub cev barrier uas kaw lub nucleus, hu ua lub hnab ntawv nuclear, tawg. https://www.nature.com › definition › prometaphase-281

metaphase, anaphase, thiab telophase. …
Yuav ua li cas thaum lub sij hawm mitotic cell division?
Thaum lub sijhawm mitosis, ib lub cell eukaryotic tau dhau los ua ua tib zoo koom tes ua haujlwm nuclear uas ua rau muaj kev tsim ntawm ob lub noob caj noob ces zoo tib yam tus ntxhais. … Tom qab ntawd, ntawm qhov tseem ceeb thaum lub sij hawm interphase (hu ua S theem), lub xov tooj ntawm tes duplicates nws chromosomes thiab xyuas kom meej tias nws cov kab ke npaj txhij rau kev faib cell.
5 theem ntawm mitotic cell division yog dab tsi?
Hnub no, mitosis tau nkag siab tias muaj tsib theem, raws li lub cev lub cev ntawm chromosomes thiab spindle. Cov theem no yog prophase, prometaphase, metaphase, anaphase, thiab telophase.
Dab tsi yog ob txheej txheem koom nrog hauv mitotic cell division?
Lub sijhawm cellKev faib ib lub xovtooj mus rau ob txoj haujlwm loj. Ua ntej, nws ua tiav mitosis, thaum lub sij hawm uas cov ntaub ntawv duplicated nyob rau hauv lub nucleus yog faib ntawm ob tug ntxhais nuclei. Cytokinesis ces tshwm sim, faib lub cytoplasm thiab cell lub cev rau hauv ob lub hlwb tshiab.
Dab tsi yog theem hauv mitotic cell division?
Mitosis muaj plaub theem: prophase, metaphase, anaphase, thiab telophase. Mitosis, txheej txheem ntawm cell duplication, los yog reproduction, thaum lub sij hawm uas ib lub cell ua rau nce mus rau ob genetic ntxhais cell cell.
