Ib zaug! Interphase yog theem ntawm qhov ntawd Dna replicates nws tus kheej. Thaum Mitosis , muaj ib tug interphase. Thaum Meiosis , kuj muaj ib qho interphase.

Hauv qhov no, DNA puas rov ua dua hauv meiosis?

DNA replication tshwm sim ib zaug thaum lub sij hawm meiosis . Cov txheej txheem yuav siv daim ntawv ntawm ib qho DNA replication tom qab ntawd los ntawm ob qhov kev faib ua tiav nuclear thiab cellular ( Meiosis kuv thiab Meiosis II). Raws li nyob rau hauv mob mitosis , meiosis yog preceded los ntawm ib tug txheej txheem ntawm DNA replication uas converts txhua chromosome rau hauv ob tug muam chromatids.
