A cell voj voog yog ib tug series ntawm cov txheej xwm uas tshwm sim nyob rau hauv ib cell raws li nws loj hlob thiab faib. A cell Nws 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 cell kev faib. Cov cell tom qab ntawd tawm hauv interphase, nkag mus rau mitosis, thiab ua tiav nws qhov kev faib tawm.

Yog li, dab tsi yog cell cycle genes?

Ntau yam ntawm noob muaj kev koom tes nyob rau hauv kev tswj ntawm cell kev loj hlob thiab kev faib . Cov cell voj voog yog cov cell cov txoj kev ntawm replicating nws tus kheej nyob rau hauv ib lub koom haum, step-by-step zam. Yog ib cell muaj qhov yuam kev hauv nws cov DNA uas tsis tuaj yeem kho tau, nws tuaj yeem raug kho cell tuag (apoptosis).

Ib tug kuj yuav nug, dab tsi yog lub luag hauj lwm ntawm lub voj voog ntawm tes? Qhov yooj yim tshaj plaws kev ua haujlwm ntawm lub voj voog ntawm tes yog kom duplicate kom raug qhov loj ntawm DNA nyob rau hauv chromosomes thiab ces cais cov ntawv luam kom meej rau hauv ob genetic ntxhais zoo tib yam. hlwb . Cov txheej txheem no txhais ob theem loj ntawm cov cell voj voog.

Ib tug kuj yuav nug, dab tsi yog lub voj voog ntawm lub xov tooj 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 . Thaum lub sij hawm mitotic theem, cov replicated chromosomes thiab cytoplasm cais ua ob tug ntxhais tshiab hlwb.

Dab tsi yog cov xwm txheej tseem ceeb ntawm lub voj voog ntawm tes?

Cov cell voj voog muab faib ua ob cov xwm txheej tseem ceeb : interphase thiab mitosis. Txawm li cas los xij, ob theem no muaj cov kev faib tawm ntxiv. Thaum lub sij hawm interphase, lub cell luam nws DNA hauv kev npaj rau mitosis. Cov theem no tau muab faib ua 3 ntu luv: G1, S thiab G2.
