Mitosis yog tus txheej txheem uas lub nucleus ntawm a eukaryotic cell faib. Thaum tus txheej txheem no, tus muam chromatids cais los ntawm txhua lwm yam thiab txav mus rau opposite ncej ntawm lub cell. Qhov no tshwm sim hauv plaub theem , hu ua prophase, metaphase, anaphase, thiab telophase.

Ntawm no, 4 theem ntawm mitosis yog dab tsi?

Mitosis muaj plaub theem pib: prophase , metaphase , anaphase , thiab telophase . Qee phau ntawv sau tsib, tawg prophase mus rau theem ntxov (hu ua prophase ) thiab theem lig (hu ua prometaphase).

Tsis tas li ntawd, cov theem ntawm cell faib yog dab tsi? Cov txheej txheem mitosis faib muaj ob peb kauj ruam lossis theem ntawm lub voj voog ntawm tes-interphase, prophase , prometaphase, metaphase , anaphase , telophase , thiab cytokinesis -kom ua tiav cov hlwb tshiab diploid.

Hauv qhov no, cov theem ntawm mitosis yog dab tsi thiab tshwm sim hauv txhua theem?

Mitosis muaj tsib theem sib txawv: interphase , prophase, metaphase , anaphase thiab telophase . Cov txheej txheem ntawm kev faib cell tsuas yog ua tiav tom qab cytokinesis, uas tshwm sim thaum lub sijhawm anaphase thiab telophase . Txhua theem ntawm mitosis yog tsim nyog rau cell replication thiab faib.

Yuav ua li cas prophase?

Thawj theem thiab ntev tshaj plaws ntawm mitosis yog prophase . Thaum prophase , chromatin condenses rau hauv chromosomes, thiab lub hnab ntawv nuclear, lossis daim nyias nyias, tawg. Nyob rau hauv cov tsiaj hlwb, cov centrioles nyob ze ntawm lub nucleus pib sib cais thiab txav mus rau opposite ncej (sab) ntawm lub cell.
