Cell voj voog kev loj hlob feem ntau tshwm sim thaum pRb yog inactivated los ntawm phosphorylation uas yog catalyzed los ntawm cyclin-dependent kinases (CDKs) nyob rau hauv complex nrog lawv cov neeg koom nrog cyclin.

Hais txog qhov no, 4 theem ntawm lub voj voog ntawm tes yog dab tsi?

Phase ntawm Cell Cycle Lub Cell Cycle yog 4-theem txheej txheem suav nrog Gap 1 (G1), Synthesis, Gap 2 (G2) thiab Mitosis . Lub active eukaryotic cell yuav ua raws li cov kauj ruam no thaum nws loj hlob thiab faib.

Yuav ua li cas tshwm sim nyob rau hauv cov theem ntawm lub cell voj voog? Cov cell voj voog muaj ob qhov loj theem : interphase thiab mitotic theem (Daim duab 1). Thaum lub sij hawm interphase, lub cell loj hlob thiab DNA yog replicated. Thaum lub sij hawm mitotic theem , cov DNA replicated thiab cytoplasmic cov ntsiab lus yog sib cais, thiab cov cell faib. Thaum lub sij hawm interphase, lub cell loj hlob thiab cov DNA DNA yog duplicated.

Ces, koj txhais li cas los ntawm cell voj voog?

Cell Cycle Txhais . Cov cell voj voog yog a lub voj voog ntawm theem uas hlwb hla dhau los tso cai rau lawv faib thiab tsim tawm tshiab hlwb . Qhov ntev tshaj plaws ntawm lub cell voj voog hu ua "interphase" - theem ntawm kev loj hlob thiab DNA replication ntawm mitotic cell kev faib.

Dab tsi yog txhais los ntawm lub voj voog ntawm tes lossis cell division voj voog?

Cell Cycle thiab Mitosis (hloov kho 2015) THE CELL CYCLE Cov cell cycle, los yog cell - kev faib voj voog , yog cov txheej xwm uas tshwm sim hauv eukaryotic cell nruab nrab ntawm nws tsim thiab lub caij nws replicates nws tus kheej. Interphase yog nyob nruab nrab ntawm lub sijhawm thaum a cell yog faib.
