cell voj voog inhibitor (sel SY-kul in-HIH-bih-ter) Ib yam khoom siv los thaiv cov Cell faib voj voog , uas yog ib tug series ntawm cov kauj ruam a cell mus dhau txhua zaus nws faib. Muaj ntau yam sib txawv ntawm cell voj voog inhibitors . Qee qhov tsuas yog ua haujlwm ntawm cov kauj ruam tshwj xeeb hauv cov cell voj voog.
Tib neeg kuj nug, dab tsi yog txhais los ntawm lub voj voog ntawm tes?
Cov cell voj voog , los yog cell - faib lub voj voog , yog series ntawm cov xwm txheej uas tshwm sim hauv ib cell ua rau duplication ntawm nws DNA (DNA replication) thiab faib cytoplasm thiab organelles los tsim ob tug ntxhais hlwb . Hauv cov kab mob, uas tsis muaj a cell nucleus, ua cell voj voog muab faib ua B, C, thiab D sijhawm.
Tom qab, lo lus nug yog, dab tsi yog cell division thiab nws hom? Muaj ob hom ntawm cell faib : mitosis thiab meiosis. Feem ntau ntawm cov sij hawm thaum tib neeg xa mus rau cell faib ,”lawv txhais tau tias mitosis, txheej txheem ntawm kev ua lub cev tshiab hlwb . Thaum lub sij hawm mitosis, a cell duplicates tag nrho cov nws cov ntsiab lus, suav nrog nws chromosomes, thiab sib cais los ua ob tug ntxhais zoo tib yam hlwb.
Cia li xav txog qhov no, lub voj voog ntawm tes ua haujlwm li cas?
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.
Dab tsi yog 3 theem ntawm lub voj voog ntawm tes?
Muaj peb theem ntawm lub voj voog ntawm tes: interphase, faib ntawm cov nucleus ( mob mitosis los yog meiosis) thiab cytokinesis. (Nco ntsoov tias muaj 3 theem hauv interphase tab sis koj tsis muaj lub luag haujlwm rau qhov no hauv koj qhov kev kawm.)
Pom zoo:
Dab tsi yog cell cycle hauv genetics?
Lub voj voog ntawm tes yog ib qho xwm txheej uas tshwm sim hauv ib lub xov tooj thaum nws loj hlob thiab faib. Ib lub xovtooj ntawm tes siv sijhawm feem ntau hauv qhov hu ua interphase, thiab lub sijhawm no nws loj hlob, rov ua dua nws cov chromosomes, thiab npaj rau kev faib cell. Tom qab ntawd lub cell tawm ntawm interphase, nkag mus rau mitosis, thiab ua tiav nws qhov kev faib tawm
Dab tsi yog qhov txawv ntawm tsiaj cell thiab cog cell?
Qhov sib txawv ntawm cov nroj tsuag thiab cov tsiaj hlwb yog tias cov tsiaj txhu feem ntau yog puag ncig thaum cov nroj tsuag feem ntau yog cov duab plaub. Cov nroj tsuag muaj cov phab ntsa tawv tawv uas nyob ib puag ncig cov cell membrane. Tsiaj cell tsis muaj phab ntsa ntawm tes
Dab tsi yog cell cycle progression?
Kev loj hlob ntawm lub voj voog ib txwm tshwm sim thaum pRb tsis ua haujlwm los ntawm phosphorylation uas yog catalyzed los ntawm cyclin-dependent kinases (CDKs) nyob rau hauv complex nrog lawv cov neeg koom nrog cyclin
Lub ntsiab lus ntawm cog cell thiab tsiaj cell yog dab tsi?
Tsiaj Thiab Nroj Tsuag Cell. Txhua yam muaj sia nyob, nroj tsuag lossis tsiaj txhu yog tsim los ntawm cov hlwb. Lub cytoplasm nyob rau hauv ib lub cell muaj chloroplast thiab lwm yam plastids, mitochondria, dictyosomes, ribosomes, du thiab ntxhib endoplasmic reticulum, nucleus thiab lwm yam. Ib tug tsiaj cell yog ntau dua los yog tsawg spherical
Dab tsi yog cell membrane hauv prokaryotic cell?
Prokaryotes thiab eukaryotes yog ob hom cell uas muaj nyob. Tab sis, prokaryotes muaj qee cov organelles nrog rau cov cell membrane, kuj hu ua phospholipid bilayer. Cov cell membrane no kaw lub cell thiab tiv thaiv nws, tso cai rau hauv qee cov molecules raws li qhov xav tau ntawm tes
