Cov ntawm tes undergoes ib hom ntawm tes faib hu ua mitosis. Hauv mitosis, ob hlwb hu ua ntxhais hlwb yog ua , txhua tus zoo tib yam rau niam txiv ntawm tes.
Ua li no, yuav faib cov cell li cas los tsim cov cell tshiab?
Thaum nws tau theej tag nrho nws cov DNA, a ntawm tes ib txwm faib rau hauv ob cov hlwb tshiab . Cov txheej txheem no hu ua mitosis. Txhua tshiab cell tau txais daim ntawv theej tag nrho ntawm DNA, suav nrog 46 chromosomes. Xovtooj uas yog ua qe los yog phev hlwb yuav tsum faib sib txawv.
Tsis tas li ntawd, vim li cas cov kab mob thiaj li tsim cov hlwb tshiab? Tag nrho cov genes ntawm ib cev ua up lub cov organis genome. Txhua kab mob ntawm tib hom muaj tib tus lej ntawm chromosomes hauv lawv cov nuclei. Txhua hlwb tsim los ntawm uas twb muaj lawm hlwb . Qhov no enables multicellular kab mob loj hlob, hloov tuag hlwb , thiab yug me nyuam.
Yog li, pes tsawg lub cell tau tsim los ntawm mitosis?
Mitosis thiab meiosis, yog li ntawd, yog cov txheej txheem zoo sib xws, tab sis ua rau muaj ntau hom hlwb. Daim duab 1. A) Hauv mitosis, ib lub xov tooj ntawm tes (lub voj voog ntawm sab laug) faib los ua ob cov ntxhais. Cov hlwb no loj tuaj, thiab tom qab ntawd faib ua tag nrho plaub lub hlwb.
Yuav ua li cas cell multiply?
Cell sib npaug los ntawm tus txheej txheem hu ua mitosis. Cov ntawm tes Lub voj voog muaj ntau theem, suav nrog interphase, mitosis thiab cytokinesis, uas ntawm tes loj hlob thiab faib ua ob tug ntxhais hlwb . Thaum kawg, thaum lub sij hawm telophase, lub hlwb tsim ob lub nuclei tshiab thiab cov chromosomes pib unwrap nws tus kheej.
