Cov ntsiab lus: Kev tswj cov qauv protein yog qhov tseem ceeb hauv kev tsim cov tshuaj ntxuav tes thiab tshuaj pleev ib ce. … Txhawm rau ntxuav cov hmoov ua haujlwm kom zoo, nws yog ib qho tseem ceeb uas cov surfactants tsis hloov cov qauv ntawm cov proteins (enzymes), vim tias kev hloov pauv hauv cov qauv enzyme tua lawv lub peev xwm los zom cov stains thiab tshem tawm. av.
tshuaj ntxuav tes cuam tshuam li cas cov qauv protein?
Cov khoom siv tshuaj ntxuav tes tau cuam tshuam los ntawm kev sim cov xwm txheej xws li concentration, kub, tsis pH thiab ionic zog, thiab muaj ntau yam additives. … Cov tshuaj ntxuav tes no cuam tshuam tag nrho cov daim nyias nyias thiab cov protein ntau los ntawm kev rhuav tshem cov protein-protein sib cuam tshuam.
Koj puas tuaj yeem hloov cov duab ntawm cov protein?
Hloov cov duab ntawm cov proteinYog tias cov protein raug hloov pauv hauv qhov kub thiab txias, pH, lossis raug tshuaj lom neeg, kev cuam tshuam sab hauv ntawm cov protein cov amino acids tuaj yeem hloov pauv, uas nyob rau hauv lem yuav hloov cov duab ntawm cov protein.
plaub yam dab tsi uas tuaj yeem hloov pauv cov duab ntawm cov protein?
Kub, pH, salinity, polarity ntawm cov kuab tshuaj - cov no yog qee yam uas cuam tshuam rau cov duab ntawm cov protein. Yog tias ib qho lossis kev sib xyaw ua ke ntawm cov xwm txheej no txawv ntawm cov xwm txheej ib txwm ua, cov duab (thiab kev ua haujlwm) ntawm cov protein yuav hloov. Qhov kev hloov pauv no tseem hu ua denatured.
Dab tsi cuam tshuam hauv cov proteintus qauv cuam tshuam los ntawm xab npum?
Cov tshuaj ntxuav tes hauv qhov chaw aqueous ntau tuaj yeem cuam tshuam cov qauv quaternary, ua kom cov qauv tertiary, ua rau cov dej-soluble domains, los yog cuam tshuam nrog cov aqueous pores ntawm membrane proteins.

Dab tsi yog qhov hloov pauv thiab hloov pauv hloov pauv?
Point mutations hloov ib leeg nucleotide. Frameshift kev hloov pauv yog ntxiv lossis tshem tawm ntawm nucleotides uas ua rau muaj kev hloov pauv hauv kev nyeem ntawv. frameshift thiab point mutation yog dab tsi? Ib qho kev hloov pauv cuam tshuam rau ib khub hauv paus.
Qhov kev hloov pauv no puas yuav ua rau muaj kev hloov pauv hloov pauv?
Yog li, yog tias muaj kev hloov pauv, piv txwv li, kev ntxig lossis tshem tawm ntawm nucleotide, tshwm sim, qhov no tuaj yeem ua rau kev hloov pauv ntawm kev nyeem ntawv. Nws hloov tag nrho cov amino acid ib ntus. Cov kev hloov pauv no yog hu ua frameshift mutation (tseem hu ua kev nyeem ntawv hloov pauv, nyeem ntawv hloov pauv, lossis framing yuam kev).
Puas yog jurassic ntiaj teb hloov pauv hloov pauv hloov pauv?

Qhov twg yog qhov kev hloov pauv hloov pauv hloov pauv?
Semiconservative replication piav qhia txog cov txheej txheem ntawm DNA replication nyob rau hauv tag nrho cov paub hlwb. DNA replication tshwm sim ntawm ntau lub hauv paus pib ntawm kev rov ua dua raws DNA qauv strand. Raws li DNA ob chav helix yog unwound by helicase, replication tshwm sim nyias ntawm txhua tus qauv strand nyob rau hauv antiparallel cov lus qhia.
Qhov kev hloov pauv twg yog xav tias yuav cuam tshuam los ntawm kev hloov pauv hloov pauv?
Dependent Variable Qhov sib txawv uas nyob ntawm lwm yam uas ntsuas. Cov kev hloov pauv no yuav tsum tau hloov pauv raws li qhov kev sim ua haujlwm ntawm tus kheej hloov pauv lossis hloov pauv. Nws yog cov nyhuv presumed. Qhov kev tshawb fawb hloov pauv twg yog qhov tshwm sim?
