Nyob ntawm kawg ntawm mitosis , ob tug ntxhais hlwb yuav yog cov ntawv luam ntawm tus thawj cell . Txhua tus ntxhais cell yuav muaj 30 chromosomes. Nyob ntawm kawg ntawm meiosis II, cwb cell (piv txwv li, gamete) yuav muaj ib nrab ntawm thawj tus lej ntawm chromosomes, uas yog, 15 chromosomes.

Tsis tas li lo lus nug yog, pes tsawg lub hlwb nyob rau qhov kawg ntawm meiosis?

Ib tug kuj yuav nug, yuav muaj pes tsawg lub hlwb thaum telophase tiav lawm? Txhua tus ntxhais cell muaj ib ua kom tiav teeb ntawm chromosomes, zoo ib yam li nws tus muam (thiab leej niam cell ). Tus ntxhais hlwb nkag rau cell lub voj voog hauv G1. Thaum twg cytokinesis tiav , peb xaus nrog ob tug tshiab hlwb , cwb a ua kom tiav teeb ntawm chromosomes zoo tib yam rau cov niam cell.

Ib tug kuj yuav nug, muaj pes tsawg lub hlwb muaj nyob rau thaum kawg ntawm cytokinesis?

- Ntawm qhov kawg ntawm cytokinesis , yuav muaj 2 tug ntxhais zoo ib yam hlwb . -Txhua tus ntxhais diploid ntxhais cell yuav muaj 46 chromosomes.

mitosis nyob qhov twg hauv lub voj voog ntawm tes?

Interphase yog qhov ntev tshaj plaws ntawm qhov cell voj voog . Qhov no yog thaum lub cell loj hlob thiab luam nws DNA ua ntej tsiv mus rau hauv mob mitosis . Thaum mob mitosis , chromosomes yuav sib dhos, sib cais, thiab txav mus rau hauv tus ntxhais tshiab hlwb . Lub prefix inter- txhais tau tias nyob nruab nrab, yog li interphase tshwm sim ntawm ib qho mitotic (M) theem thiab tom ntej.
