Mitosis yog hom qub cell faib . Ua ntej lub hlwb ua tau faib , cov chromosomes yuav muaj duplicated thiab cov cell yuav muaj ob npaug ntawm cov txheej txheem ib txwm muaj. Thawj kauj ruam ntawm cell faib yog prophase, thaum lub sij hawm lub nucleus yaj thiab cov chromosomes pib migration mus rau lub midline ntawm lub cell.

Tom qab ntawd, ib tus tuaj yeem nug, qhov twg theem ntawm lub voj voog ntawm tes cuam tshuam nrog kev faib tawm ntawm lub cell lub nucleus?

Mitosis

Ib sab saum toj no, thaum lub sij hawm twg ntawm cov cell faib ua lub nuclear membrane yaj? prophase

Kuj nug, nyob rau theem twg yog lub cell ua ntej mitosis pib?

Cov cell lub voj voog muaj peb theem uas yuav tsum tshwm sim ua ntej mitosis , los yog cell kev faib, tshwm sim. Cov peb theem no yog sib sau ua ke hu ua interphase. Lawv yog G1, S, thiab G2. G sawv rau qhov sib txawv thiab S sawv rau kev sib txuas.

Nyob rau theem twg cell division tshwm sim?

Mitosis (tus M theem ) Cov txheej txheem ntawm mob mitosis , los yog cell faib , tseem hu ua M theem . Qhov no yog qhov twg cell faib nws yav dhau los-tshaj DNA thiab cytoplasm los ua ob tus ntxhais tshiab, zoo ib yam hlwb . Mitosis muaj plaub yam yooj yim theem : prophase, metaphase, anaphase, thiab telophase.
