Video: Dab tsi yog 6 theem ntawm lub voj voog ntawm tes hauv kev txiav txim?
2024 Tus sau: Miles Stephen | [email protected]. Kawg hloov kho: 2023-12-15 23:36
Cov theem no yog prophase , prometaphase, metaphase , kev anaphase , thiab telophase.
Ib yam li ntawd ib tug yuav nug, dab tsi yog qhov tseeb ntawm cov xwm txheej hauv lub voj voog ntawm tes?
Cov cell voj voog yog plaub-theem txheej txheem uas cov cell nce qhov loj me (kawg 1, lossis G1, theem), theej nws cov DNA (synthesis, lossis S, theem), npaj sib faib (kawg 2, lossis G2, theem), thiab faib (mitosis, lossis M, theem). Cov theem G1, S, thiab G2 ua interphase, uas suav rau qhov nruab nrab ntawm cell kev faib.
Qhov thib ob, dab tsi yog theem ntawm lub voj voog ntawm tes nyob rau hauv kev txiav txim txij thaum pib mus txog thaum xaus? 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. Tom qab ua tiav lub voj voog, lub xov tooj ntawm tes yuav pib txheej txheem dua los ntawm G1 lossis tawm ntawm lub voj voog mus txog G0.
Ntawm no, qhov kev txiav txim ntawm cov theem mitosis yog dab tsi?
Cov theem ntawm mob mitosis : prophase, metaphase, anaphase, telophase. Cytokinesis feem ntau sib tshooj nrog anaphase thiab / lossis telophase. Koj tuaj yeem nco txog xaj ntawm theem nrog lub npe nrov mnemonic: [Thov] Pee ntawm MAT.
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 replicated DNA thiab cytoplasmic 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 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
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
Dab tsi yog qhov kev txiav txim kom raug rau cov kev cuam tshuam ntawm Calvin lub voj voog?
Daim Ntawv Teev Npe 1. Dab tsi yog qhov yuav tsum tau ua rau lub teeb pom kev ntawm photosynthesis? Lus Txhais Lus Carbon Dioxide Term 19. Yuav ua li cas yog qhov kev txiav txim rau cov kev tshwm sim ntawm Calvin-Benson voj voog? Lus txhais c. carbon fixation, synthesis ntawm G3P, regeneration ntawm RuBP
