Vaj Huam Sib Luag 18-1

Tsib theem ntawm mitosis - prophase , prometaphase, metaphase , anaphase , thiab telophase - tshwm sim nyob rau hauv nruj sequential kev txiav txim, thaum cytokinesis pib hauv anaphase thiab txuas ntxiv mus telophase.

Tib neeg kuj nug, dab tsi yog theem ntawm mitosis hauv cov nroj tsuag?

Cog mitosis yog ib feem ntawm cov nroj tsuag cell faib qhov twg cov chromosomes replicated tau muab cais ua ob, tus ntxhais nuclei. Nws tshwm sim hauv plaub theem, tib yam li tsiaj mitosis. Cov theem no yog prophase, metaphase , anaphase , thiab telophase.

Tom qab ntawd, lo lus nug yog, dab tsi yog 6 theem ntawm mitosis? Cov theem no yog prophase , prometaphase, metaphase , anaphase , thiab telophase . Cytokinesis yog qhov kawg ntawm lub cev ntawm tes faib ua raws li hauv qab no telophase , thiab yog li qee zaum suav tias yog theem thib rau ntawm mitosis.

Tom qab ntawd, lo lus nug yog, dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau ntawm tes hauv txhua theem?

Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub sij hawm uas lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws DNA mus rau ob lub hlwb zoo tib yam.

Cov nroj tsuag puas ua mitosis?

Nroj tsuag thiab tsiaj hlwb ob leeg undergo mitotic cell kev faib. Lawv lub ntsiab txawv yog li cas lawv tsim tus ntxhais hlwb thaum lub sij hawm cytokinesis. Thaum lub sij hawm ntawd, tsiaj hlwb daim ntawv furrow los yog cleavage uas muab txoj kev rau tsim ntawm tus ntxhais hlwb . Vim muaj qhov nruj cell phab ntsa, cog hlwb tsis txhob tsim furrows.
