Mitosis yog tus txheej txheem uas lub nucleus ntawm ib tug eukaryotic cell faib. Thaum lub sijhawm txheej txheem no, tus muam chromatids cais tawm ntawm ib leeg thiab txav mus rau cov ncej ntawm tes. Qhov no tshwm sim hauv plaub theem , hu ua prophase, metaphase, anaphase, thiab telophase.
Raws li txoj cai, cov theem ntawm mitosis yog dab tsi thiab tshwm sim hauv txhua theem?
Mitosis muaj tsib theem sib txawv: interphase, prophase, metaphase , kev anaphase thiab telophase . Cov txheej txheem ntawm kev faib cell tsuas yog ua tiav tom qab cytokinesis, uas tshwm sim thaum lub sijhawm kev anaphase thiab telophase . Txhua theem ntawm mitosis yog tsim nyog rau cell replication thiab faib.
Tom qab, lo lus nug yog, ua li cas thaum lub sij hawm mitosis? Thaum lub sij hawm mitosis , ib lub cell eukaryotic tau ua tib zoo ua tib zoo sib koom ua ke nuclear kev faib tawm uas ua rau tsim ntawm ob lub noob caj noob ces zoo tib yam tus ntxhais. Mitosis Nws tus kheej muaj tsib theem ua haujlwm, lossis theem: prophase, prometaphase, metaphase, anaphase, thiab telophase.
Ib yam li ntawd, 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.
Cov txheej txheem mitosis yog dab tsi?
Mitosis yog a txheej txheem ntawm nuclear faib nyob rau hauv eukaryotic hlwb uas tshwm sim thaum ib tug niam txiv cell faib los tsim ob tug zoo tib yam cov ntxhais hlwb. Cov mitotic spindle txuas los ntawm tus ncej thiab txuas mus rau kinetochores.

Yuav ua li cas tshwm sim rau tam sim no nyob rau hauv ib tug parallel circuits thaum ntxiv qhov muag teev?
Raws li ntau qhov muag tau ntxiv, qhov tam sim no nce. Raws li ntau resistors ntxiv nyob rau hauv parallel, tag nrho tam sim no lub zog nce. Yog li ntawd, tag nrho cov tsis kam ntawm Circuit Court yuav tsum tau txo. Qhov tam sim no nyob rau hauv txhua lub teeb yog tib yam vim hais tias tag nrho cov qhov muag teev glowed nrog tib brightness
Yuav ua li cas tshwm sim nyob rau hauv synthesis theem?
S theem, los yog synthesis, yog theem ntawm lub voj voog ntawm tes thaum DNA ntim rau hauv chromosomes replicated. Qhov kev tshwm sim no yog ib qho tseem ceeb ntawm lub voj voog ntawm tes vim tias kev rov ua dua tso cai rau txhua lub cell tsim los ntawm kev faib cell kom muaj tib yam caj ces tsim
Yuav ua li cas tshwm sim nyob rau hauv lub kub foil sim?
Physicist Ernest Rutherford tau tsim lub tswv yim nuclear ntawm lub atom nrog nws qhov kev sim kub-txheej txheem. Thaum nws tua ib tug beam ntawm alpha hais ntawm ib daim ntawv ntawm kub ntawv nyiaj, ob peb ntawm cov hais tau deflected. Nws xaus lus tias ib tug me me, ntom nucleus ua rau deflections
Yuav ua li cas tshwm sim rau qhov teeb meem uas ploj ntawm txhua theem ntawm cov khoom noj khoom haus?
Lub zog tau dhau los ntawm cov khoom noj khoom haus los ntawm ib qib trophic mus rau lwm qhov. Txawm li cas los xij, tsuas yog kwv yees li 10 feem pua ntawm tag nrho lub zog khaws cia hauv cov kab mob ntawm ib qib trophic tau raug xa mus rau cov kab mob ntawm qib trophic tom ntej. Cov seem ntawm lub zog yog siv rau cov txheej txheem metabolic lossis poob rau ib puag ncig raws li cua sov
Yuav ua li cas tshwm sim nyob rau hauv txhua ntawm 4 theem ntawm mitosis?
Mitosis yog cov txheej txheem uas cov nucleus ntawm eukaryotic cell faib. Thaum lub sijhawm txheej txheem no, tus muam chromatids cais tawm ntawm ib leeg thiab txav mus rau cov ncej ntawm tes. Qhov no tshwm sim nyob rau hauv plaub theem, hu ua prophase, metaphase, anaphase, thiab telophase
