Nyob hauv tib neeg, DNA pom muaj nyob hauv lub nucleus ntawm cell. Cov txheej txheem ntawm replication (uas luam DNA) yuav tsum muaj nyob rau hauv lub nucleus vim qhov no yog qhov twg DNA tau pom.
Thaum twg thiab qhov twg replication tshwm sim?
Replication tshwm sim hauv lub nucleus thaum lub sijhawm S theem ntawm lub voj voog ntawm tes hauv eukaryotes, thiab rov ua dua tshiab tshwm sim tsis tu ncua hauv prokaryotes.
replication nyob rau hauv lub cell nyob qhov twg?
DNA replication tshwm sim hauv the nucleus. DNA transcription tshwm sim nyob rau hauv lub nucleus. mRNA kev txhais lus tshwm sim ntawm ribosomes.
txheej txheem rov ua dua nyob qhov twg?
DNA replication tshwm sim nyob rau hauv cytoplasm ntawm prokaryotes thiab nyob rau hauv lub nucleus ntawm eukaryotesTxawm hais tias qhov twg DNA replication tshwm sim, cov txheej txheem tseem ceeb yog tib yam. Cov qauv ntawm DNA qiv nws tus kheej yooj yim rau DNA replication. Txhua sab ntawm ob lub helix khiav nyob rau hauv opposite (anti-parallel) cov lus qhia.
Vim li cas rov ua dua nyob rau hauv lub nucleus?
Lub nucleus muaj ib lossis ntau dua nucleoli, uas yog qhov chaw rau ribosome synthesis. Lub nucleus tsev cov khoom siv caj ces ntawm lub cell: DNA. … Ua ntej ib lub xov tooj yuav npaj txhij los faib, nws yuav tsum rov ua dua nws cov DNA thiaj li tias txhua tus ntxhais tshiab ntawm tes yuav tau txais ib daim qauv ntawm cov kab mob genome
