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.)
