Tom qab metaphase tiav, lub xovtooj enters anaphase. Thaum lub sij hawm anaphase, cov microtubules txuas nrog rau daim ntawv cog lus kinetochore, uas rub tus viv ncaus chromatids sib nrug thiab mus rau cov ncej ntawm tes (Daim duab 3c).
7 theem ntawm mitosis yog dab tsi?
Cov theem no yog prophase, prometaphase, metaphase, anaphase, thiab telophase. Cytokinesis yog qhov kawg ntawm lub cev ntawm tes faib ua raws li telophase, thiab yog li qee zaum suav tias yog theem thib rau ntawm mitosis.
4 theem ntawm mitosis yog dab tsi thiab tshwm sim hauv txhua qhov?
Cov txheej txheem uas cov nucleus ntawm eukaryotic cell faib yog hu ua mitosis. Thaum lub sij hawm mitosis, ob tus viv ncaus chromatids uas ua rau txhua tus chromosome cais tawm ntawm ib leeg thiab txav mus rau cov ncej ntawm tes. Mitosis tshwm sim hauv plaub theem. Cov theem hu ua prophase, metaphase, anaphase, thiab telophase.
Qhov twg yog qhov tseeb ntawm cov xwm txheej hauv mitosis?
theem ntawm mitosis: prophase, metaphase, anaphase, telophase. Cytokinesis feem ntau sib tshooj nrog anaphase thiab / lossis telophase. Koj tuaj yeem nco qab qhov kev txiav txim ntawm theem nrog lub npe nrov mnemonic: [Thov] Pee ntawm MAT.
theem ua raws li metaphase?
Metaphase follows prophase. Thaum lub sij hawm metaphase, cov chromosomes nyob rau hauv nruab nrab ntawm lub cell ntawm lub equatorial phaj thiab cov spindle fibers txuas mus rau lub centromeres ntawm cov chromosomes. Anaphase koom nrogretraction ntawm spindle fibers thiab kev sib cais ntawm tus muam chromatids.
