Cov S theem ntawm a cell voj voog tshwm sim Thaum lub sij hawm interphase, ua ntej mitosis los yog meiosis, thiab yog lub luag hauj lwm rau cov synthesis los yog replication ntawm DNA. Nyob rau hauv no txoj kev, genetic khoom ntawm a cell yog ob npaug ua ntej nws nkag mus rau mitosis lossis meiosis, tso cai kom muaj DNA txaus los faib ua tus ntxhais hlwb.

Nyob rau hauv txoj kev no, yuav ua li cas tshwm sim thaum lub sij hawm S theem ntawm lub cell quizlet?

Cov cell npaj rau kev faib thiab luam organelles. Dab tsi tshwm sim thaum lub sij hawm S ? Cov cell cov DNA yog theej nyob rau hauv tus txheej txheem ntawm DNA replication.

Ib tug kuj nug, vim li cas S theem ntawm lub voj voog ntawm tes yog qhov tseem ceeb rau kev faib cell? S theem , los yog synthesis, yog cov theem ntawm lub voj voog ntawm tes thaum DNA ntim rau hauv chromosomes replicated. Qhov kev tshwm sim no yog ib qho qhov tseem ceeb nam ntawm cell voj voog vim replication pub rau txhua tus cell tsim los ntawm cell faib kom muaj tib yam tshuaj genetic make-up.

Ntawm no, dab tsi tshwm sim hauv g2 theem ntawm lub voj voog ntawm tes?

Qhov kawg ntawm interphase yog hu ua G2 Phase . Cov cell tau loj hlob, DNA tau replicated, thiab tam sim no lub cell yuav luag npaj faib. Qhov kawg theem no yog tag nrho hais txog prepping lub cell rau mitosis los yog meiosis. Thaum lub sij hawm G2 Phase , cov cell yuav tsum loj hlob ib co ntxiv thiab tsim tej molecules nws tseem yuav tsum tau faib.

Dab tsi tshwm sim hauv g1 theem?

Cov G1 Phase feem ntau hu ua kev loj hlob theem , vim qhov no yog lub sijhawm uas lub cell loj hlob. Lub sijhawm no theem , lub cell synthesizes ntau yam enzymes thiab cov as-ham uas xav tau tom qab rau DNA replication thiab cell division. Cov G1 Phase kuj yog thaum cov hlwb tsim cov protein ntau.
