Interphase yog ib theem ntawm lub voj voog ntawm tes, txhais tau tias tsuas yog qhov tsis muaj cell faib. Thaum lub sij hawm interphase, lub cell tau txais cov as-ham, thiab duplicates (copy) nws cov chromatids (genetic khoom). Cov genetic khoom los yog chromatids nyob rau hauv lub nucleus ntawm lub cell thiab yog ua los ntawm cov molecule DNA.
Yuav ua li cas rov ua dua thaum lub sijhawm cuam tshuam?
Nyob rau hauv interphase, lub cell loj hlob thiab DNA yog replicated. … Thaum lub sij hawm interphase, lub xov tooj ntawm tes loj hlob thiab lub nuclear 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.
Thaum lub sijhawm twg ntawm kev sib cuam tshuam yog cov khoom siv caj ces rov ua dua?
The S Phase of Interphase The S Phase of InterphaseS Theem S ntawm lub voj voog ntawm tes 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.
Yuav ua li cas genetic khoom replicates?
DNA replicates hauv the S theem ntawm lub voj voog ntawm tes thiab pib ntawm thaj chaw tshwj xeeb hauv DNA ib ntus hu ua DNA replication 'keeb kwm'. Ib tug xov tooj ntawm cov proteins koom rau hauv DNA replication thiab cov txheej txheem yuav raug soj ntsuam los ntawm cell soj ntsuam mechanisms hu ua cell cycle checkpoints.
Cov khoom genetic tshwm sim li cas thaum lub sij hawm interphase?
Nyob rau hauv interphase (1), chromatin yog nyob rau hauv nwstsawg kawg condensed lub xeev thiab zoo li xoob faib thoob plaws hauv lub nucleus. Chromatin condensation pib thaum lub sij hawm prophase (2) thiab chromosomes pom. Chromosomes tseem condensed thoob plaws hauv ntau theem ntawm mitosis (2-5).
