Ua ke, G1, S, thiab G2 Phase ua rau lub sijhawm hu ua interphase . Cells feem ntau siv sij hawm ntau nyob rau hauv interphase tshaj lawv ua hauv mob mitosis . Ntawm plaub theem, G1 yog qhov sib txawv tshaj plaws ntawm lub sijhawm, txawm hais tias nws feem ntau yog qhov ntev tshaj plaws ntawm lub voj voog ntawm tes (Daim duab 1).

Kuj paub, dab tsi yog qhov tseem ceeb tshaj plaws ntawm mitosis?

Interphase

Tsis tas li ntawd, vim li cas lub voj voog ntawm tes tseem ceeb? Cov cell voj voog yog replication thiab luam tawm ntawm hlwb , txawm nyob rau hauv eukaryotes los yog prokaryotes. Nws yog tseem ceeb rau cov kab mob sib txawv, tab sis tag nrho nws tso cai rau lawv kom muaj sia nyob. Rau cov prokaryotes, cell voj voog , hu ua Binary Fission, tso cai rau lawv ua neej nyob los ntawm kev faib ua ob tug ntxhais tshiab hlwb.

Kuj Paub, dab tsi yog lub sij hawm luv tshaj ntawm lub voj voog ntawm tes?

Mitosis muab faib ua plaub theem: prophase, metaphase, anaphase , thiab telophase. Lub sijhawm luv tshaj plaws ntawm lub voj voog ntawm tes yog hu ua cytokinesis (kev faib tawm ntawm cytoplasm).

Dab tsi theem cell cleaved ua ob?

Lub Mitotic Theem . Lub mitotic theem yog ib qho txheej txheem multistep thaum lub sij hawm uas cov chromosomes duplicated yog ua raws, sib cais, thiab txav mus ua ob tshiab, zoo tib yam ntxhais hlwb . Thawj feem ntawm mitotic theem hu ua karyokinesis, los yog nuclear division.
