Thaum Mitosis, DNA tau rov ua dua thaum the S (Synthesis theem Synthesis theem S (Synthesis Phase) yog theem ntawm lub voj voog ntawm tes uas DNA rov ua dua , tshwm sim Nyob nruab nrab ntawm G1 theem thiab G2 theem. tswj hwm thiab khaws cia dav dav. https://en.wikipedia.org › wiki › S_phase
S theem - Wikipedia
) ntawm Interphase. Interphase yog qhov pib lub neej txhua hnub ntawm lub xov tooj ntawm tes. Cells siv feem ntau ntawm lawv lub neej hauv Interphase ua ntej Mitosis tshwm sim (M theem).
DNA replication tshwm sim nyob rau theem twg?
Nyob rau hauv lub voj voog ntawm eukaryotic cell, chromosome duplication tshwm sim thaum " S theem" (theem ntawm DNA synthesis) thiab chromosome segregation tshwm sim thaum "M theem" (theem mitosis).
Puas yog DNA rov ua dua hauv meiosis mitosis lossis ob qho tib si?
Yog, DNA rov ua dua hauv ob qho tib si mitosis thiab meiosis. Hauv meiosis, lub xovtooj ntawm tes raug faib ua ob ntu, piv txwv li meiosis I thiab II. Meiosis I yog txo kev faib thiab meiosis II zoo ib yam li mitosis tab sis DNA replicates ib zaug thaum lub sij hawm meiosis, piv txwv li ua ntej meiosis I nyob rau hauv S theem.
Thaum twg DNA rov tshwm sim thaum lub sijhawm meiosis?
2) Tawm ntawm txhua theem DNA rov ua dua tsuas yog tshwm sim hauv the S theem ntawm meiosis. Tag nrho meiosis cell voj voog tsuas muaj ib theem S uas txhais tau hais tias DNA yuav tau rov ua dua ib zaug hauv tag nrho cov kev faib meiotic.
Lub sijhawm twg ntawm lub voj voog ntawm tes puas DNA rov ua dua?
The S lossis synthesis theem yog thaum DNA rov tshwm sim, thiab theem M lossis mitosis yog thaum lub cell sib faib.
