Qhov Tseem Ceeb Qhov txawv - Karyokinesis vs Cytokinesis
Nyob rau hauv cov ntsiab lus ntawm lub voj voog ntawm tes muaj ob qhov kev faib loj uas tshwm sim thaum lub sij hawm faib cell. Lub cell faib theem muaj xws li ob qho tib si mitosis thiab meiosis theem. Ob qhov kev faib tseem ceeb suav nrog kev faib cov nucleus thiab faib cov cytoplasm. Karyokinesis yog hu ua cov txheej txheem uas cov nucleus faib los ua tus ntxhais nuclei los ntawm mitosis lossis meiosis. Cytokinesis hais txog cov txheej txheem ntawm kev faib cov cell cytoplasm nyob rau hauv cov tsiaj hlwb uas ua rau cov ntxhais cell tom qab ua tiav ntawm lub voj voog ntawm tes. Qhov sib txawv tseem ceeb ntawm karyokinesis thiab cytokinesis yog physiology ntawm cov txheej txheem. Thaum lub sij hawm Karyokinesis, lub cell nucleus faib thaum lub sij hawm cytokinesis, lub cell cytoplasm ntawm cov tsiaj cell faib los ua cov ntxhais hlwb.
Karyokinesis yog dab tsi?
Karyokinesis yog cov txheej txheem uas cov cell nucleus faib thaum lub sijhawm faib cell ntawm lub voj voog ntawm tes. Karyokinesis tshwm sim hauv ob qho tib si mitosis thiab meiosis. Mitotic cell division yog siv, txhawm rau piav qhia cov txheej txheem ntawm Karyokinesis. Karyokinesis lossis nuclear kev faib ua haujlwm nyob rau hauv plaub theem nyob rau hauv mitotic cell division. Cov theem ntawm karyokinesis yog; Prophase, Metaphase, Anaphase thiab Telophase. Thaum lub sij hawm Prophase, chromosome condensation tshwm sim. Cov chromosomes replicated yog untangled nyob rau hauv cov kauj ruam no. Cov viv ncaus condensed chromatids yog khi ua ke ntawm centromere. Cov chromosomes txav mus rau ob tug ncej ntawm lub nucleus. Lub mitotic spindle kuj tsim nyob rau theem no.
Daim duab 01: Karyokinesis
Nyob rau hauv Metaphase, cov microtubules ntawm spindle apparatus txuas rau cov chromosomes ntawm lub kinetochore proteins ntawm lub centromere. Cov chromosomes ces teem rau ntawm lub dav hlau equatorial ntawm lub nucleus. Cov theem tom ntej yog theem Anaphase. Thaum lub sij hawm tus muam chromatids cais ntawm lub centromere. Cov chromatids teeb tsa hauv U duab ntawm lub dav hlau equatorial. Thaum lub sijhawm kawg ntawm theem mitosis lossis thaum lub sijhawm Telophase, lub hnab ntawv nuclear tau hloov kho, thiab cytokinesis yuav siv qhov chaw cais cov hlwb.
Cytokinesis yog dab tsi?
Cytokinesis yog theem kawg ntawm lub voj voog ntawm tes uas ua rau ob tug ntxhais. Cytokinesis yog hu ua kev faib ntawm cov cell cytoplasm. Cov txheej txheem Cytokinesis pib thaum kawg ntawm Anaphase ntawm kev faib nuclear. Hauv cov tsiaj hlwb, cytokinesis yog kho los ntawm lub nplhaib ntawm actin thiab myosin filaments. Cov filaments no tsim ib lub hnab hauv qab cov plasma membrane. Lub nplhaib no thaum kawg yuav txiav txim siab qhov cleavage ntawm cell cytoplasm. Lub cleavage yuav siv qhov chaw perpendicular mus rau spindle. Cov cleavage ua rau kev sib cog lus ntawm actin thiab myosin filaments uas ua rau rub lub plasma membrane thiab cell yog cleaved rau hauv ob halves.
Daim duab 02: Cytokinesis
Nyob hauv cov nroj tsuag, cov txheej txheem cytokinesis txawv raws li nws tsim lub dav hlau ntawm tes uas nws thiaj li ua rau cov phab ntsa ntawm tes.
Dab tsi yog qhov zoo sib xws ntawm Karyokinesis thiab Cytokinesis?
- Ob leeg karyokinesis thiab cytokinesis tshwm sim thaum lub sijhawm faib cell ntawm lub voj voog ntawm tes.
- Karyokinesis thiab cytokinesis yog ob ntu ntawm lub voj voog ntawm tes.
- Ob leeg karyokinesis thiab cytokinesis koom nrog hauv kev tsim cov menyuam ntxhais.
- Ob leeg karyokinesis thiab cytokinesis yog qhov tseem ceeb hauv kev loj hlob thiab kev loj hlob ntawm lub cev.
Qhov txawv ntawm Karyokinesis thiab Cytokinesis yog dab tsi?

Summary – Karyokinesis vs Cytokinesis
Karyokinesis thiab Cytokinesis yog ob txheej txheem uas tseem ceeb hauv cov txheej txheem ntawm kev faib cell ntawm eukaryotic hlwb. Karyokinesis hais txog cov txheej txheem uas lub nucleus faib los ua ob tug ntxhais nuclei. Cytokinesis hais txog cov txheej txheem uas cov cytoplasm faib ua ob lub hlwb. Karyokinesis tshwm sim nyob rau hauv ob qho tib si mitosis thiab meiosis thiab pib nyob rau hauv thawj theem ntawm cell faib. Cytokinesis tshwm sim los ntawm kev tsim ntawm actin thiab myosin filaments, thiab los ntawm kev sib cais tawm, lub cytoplasm yog cleaved rau hauv ob halves. Karyokinesis ua raws li cytokinesis. Qhov no yog qhov txawv ntawm karyokinesis thiab cytokinesis.
