Phase. Lub voj voog ntawm eukaryotic cell muaj plaub theem: G1 Phase, S theem (synthesis), G2 theem (collectively hu ua interphase) thiab M theem ( mob mitosis thiab cytokinesis).
Cov lus nug tseem yog, plaub theem ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim hauv txhua theem?
Lub voj voog ntawm tes yog txheej txheem plaub-theem uas lub xov tooj ntawm tes nce qhov loj (kawg 1, lossis G1, theem), theej nws cov DNA (synthesis, lossis S, theem), npaj los faib (kawg 2, lossis G2, theem), thiab faib ( mob mitosis , los yog M, theem). Cov theem G1, S, thiab G2 ua rau interphase, uas suav nrog kev ncua ntawm kev faib cell.
Tsis tas li ntawd, 4 theem ntawm mitosis yog dab tsi thiab dab tsi tshwm sim hauv txhua qhov? Mitosis yog tus txheej txheem uas lub nucleus ntawm ib tug 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.
Kuj tseem yuav paub, dab tsi tshwm sim hauv cov theem ntawm lub voj voog ntawm tes?
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.
Lub neej voj voog ntawm tes yog dab tsi?
Cov cell voj voog ( cell - faib lub voj voog ), yog cov xwm txheej uas tshwm sim hauv ib cell ua rau nws faib thiab duplication. Lub ntsiab theem ntawm lub cell voj voog yog interphase, nuclear division, thiab cytokinesis. Hauv hlwb tsis muaj nucleus (prokaryotic), lub cell voj voog tshwm sim ntawm binary fission.

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Dab tsi yog 6 theem ntawm lub voj voog ntawm tes hauv kev txiav txim?
Cov theem no yog prophase, prometaphase, metaphase, anaphase, thiab telophase
Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum 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 cov DNA mus rau ob lub hlwb zoo tib yam
Dab tsi yog txhais los ntawm lub voj voog ntawm tes lossis cell division voj voog?
Cell Cycle thiab Mitosis (hloov kho 2015) LUB CELL CYCLE Lub voj voog ntawm tes, lossis lub voj voog ntawm tes faib, yog cov xwm txheej uas tshwm sim hauv lub cell eukaryotic ntawm nws qhov tsim thiab lub sijhawm nws rov ua dua nws tus kheej. Interphase yog nyob nruab nrab ntawm lub sijhawm thaum lub cell faib
Dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
