The S Phase ntawm Interphase Ua li no, cov khoom siv caj ces ntawm lub xov tooj ntawm tes yog ob npaug ua ntej nws nkag mus rau mitosis lossis meiosis, tso cai kom muaj DNA txaus los faib ua tus ntxhais. hlwb. Lub S theem tsuas yog pib thaum lub xovtooj tau dhau G 1 { G }_{ 1 } G1 checkpoint thiab tau loj hlob txaus kom muaj ob npaug ntawm DNA.
Lub sijhawm twg ntawm lub voj voog ntawm tes ncaj qha ua ntej mitosis?
Interphase yog qhov ntev tshaj plaws ntawm lub voj voog ntawm tes. Qhov no yog thaum lub cell loj hlob thiab luam nws cov DNA ua ntej tsiv mus rau mitosis. Thaum lub sij hawm mitosis, chromosomes yuav sib dhos, sib cais, thiab txav mus rau hauv cov ntxhais tshiab.
Qhov kev txiav txim ntawm Subphases ntawm interphase yog dab tsi?
Interphase yog tsim los ntawm G1 theem (kev loj hlob ntawm tes), ua raws li S theem (DNA synthesis), ua raws li G2 theem (kev loj hlob ntawm tes). Thaum kawg ntawm interphase los ntawm mitotic theem, uas yog tsim los ntawm mitosis thiab cytokinesis thiab ua rau tsim ntawm ob tug ntxhais hlwb.
Puas interphase precede mitosis?
Interphase tshwm sim ua ntej pib ntawm mitosis thiab suav nrog qhov hu ua theem G1, lossis thawj qhov sib txawv, theem S, lossis kev sib txuas, thiab theem G2, lossis qhov sib txawv thib ob. Qib G1, S, thiab G2 yuav tsum tshwm sim nyob rau hauv qhov kev txiav txim no. Lub voj voog ntawm tes pib nrog theem G1, uas yog ib feem ntawm interphase.
Yuav ua li cas hauv Subphases ntawm interphase?
Lub sijhawminterphase, lub xovtooj loj hlob thiab cov DNA DNA yog duplicated. Interphase yog ua raws li theem mitotic. Thaum lub sij hawm mitotic theem, cov duplicated chromosomes yog segregated thiab faib mus rau hauv tus ntxhais nuclei. Lub cytoplasm feem ntau yog muab faib ib yam nkaus, ua rau ob tug ntxhais hlwb.
