Transcription yog txheej txheem ntawm kev ua ib daim ntawv RNA ntawm ib tug gene sequence. Kev txhais lus yog tus txheej txheem ntawm txhais qhov sib lawv liag ntawm tus tub txib RNA molecule rau ib theem ntawm cov amino acids thaum lub sij hawm protein synthesis. Thaum kawg, qhov no yog txhua yam peb paub txog transcription thiab translation ntawm cov noob caj noob ces.
Ib yam li ntawd, nws yog nug, dab tsi yog transcription thiab txhais lus?
DNA, RNA thiab protein synthesis Qhov no yog lub npe hu ua tib neeg genome. Cov txheej txheem uas DNA tau theej rau RNA hu ua kev sau ntawv , thiab qhov uas RNA siv los tsim cov proteins hu ua txhais lus.
Tsis tas li ntawd, qhov sib txawv ntawm kev txhais lus thiab kev hloov pauv hauv DNA replication yog dab tsi? Qhov txawv . DNA replication tshwm sim nyob rau hauv kev npaj rau cell division, thaum kev sau ntawv tshwm sim hauv kev npaj rau cov protein txhais lus . DNA replication Nws yog ib qho tseem ceeb rau kev tswj cov kev loj hlob thiab kev faib ntawm cov hlwb kom zoo.
Tsis tas li lo lus nug yog, dab tsi yog qhov kev hloov pauv thiab kev txhais lus hauv protein synthesis?
Cell siv cov noob rau synthesize cov protein . Qhov no yog ob kauj ruam txheej txheem. Thawj kauj ruam yog kev sau ntawv nyob rau hauv uas ib theem zuj zus ntawm ib noob yog replicated nyob rau hauv ib tug RNA molecule. Cov kauj ruam thib ob yog txhais lus nyob rau hauv uas RNA molecule ua hauj lwm raws li ib tug cai rau tsim ib tug amino-acid saw (polypeptide).
Dab tsi yog qhov txawv ntawm kev sau ntawv thiab kev txhais lus quizlet?
Kev sau ntawv yog cov synthesis ntawm RNA los ntawm DNA. tshwm sim hauv nucleus. Kev txhais lus yog cov synthesis ntawm cov protein los ntawm RNA.

Cov ntsiab lus hydrophilic thiab hydrophobic txhais li cas thiab lawv cuam tshuam li cas?
Hydrophobic txhais tau hais tias cov molecule yog "ntshai" dej. Cov tails ntawm phospholipid yog hydrophobic, txhais tau tias lawv nyob hauv daim nyias nyias. Hydrophilic txhais tau hais tias cov molecule muaj affinity rau dej
Vim li cas A thiab T thiab G thiab C ua khub hauv DNA ob lub helix?
Qhov no txhais tau hais tias txhua ntawm ob strandsindouble-stranded DNA ua raws li ib tug templatetoproduce ob strands tshiab. Replication relies oncomplementary basepairing, uas yog lub hauv paus ntsiab lus piav qhia los ntawmChargaff cov cai: adenine (A) ib txwm khi nrog thymine (T) thiab cytosine (C) ib txwm khi nrog guanine (G)
Yuav ua li cas hloov kho ua ntej mRNA ntawm transcription thiab translation?
Lub pre-mRNA yuav tsum dhau los ntawm qee qhov kev hloov kho kom dhau los ua mRNA molecule uas paub tab uas tuaj yeem tawm hauv lub nucleus thiab raug txhais. Cov no suav nrog splicing, capping, thiab ntxiv ntawm poly-A tail, tag nrho cov uas muaj peev xwm tswj tau - sped up, slowed down, los yog hloov mus rau ib tug txawv cov khoom
Dab tsi yog qhov txawv ntawm Arrhenius txhais thiab brønsted Lowry txhais ntawm acids thiab bases?
Qhov txawv ntawm peb txoj kev xav yog qhov kev xav Arrhenius hais tias cov kua qaub ib txwm muaj H + thiab cov hauv paus ib txwm muaj OH-. Thaum tus qauv Bronsted-Lowry thov tias cov kua qaub yog cov neeg pub dawb proton thiab cov neeg txais kev lees paub yog li cov hauv paus tsis tas yuav muaj OH- yog li cov kua qaub pub ib qho proton rau dej tsim H3O +
Transcription txhais li cas hauv kev sau ntawv?
: kev ua lossis txheej txheem ntawm kev sau ntawv, luam tawm, lossis ntaus ntawv luam ntawm cov lus uas tau hais. Saib tag nrho cov ntsiab lus rau kev sau ntawv hauv Lus Askiv Cov Neeg Kawm Lus Askiv
