pib complex txhais. Cov complex tsim rau pib ntawm kev txhais lus. Nws muaj 30S ribosomal subunit; mRNA; N-formyl-methionine tRNA; thiab peb pib yam.
Ib yam li ib tug yuav nug, dab tsi yog qhov pib ua haujlwm?
Protein Synthesis thiab Degradation Lub 70S pib complex yog tsim raws li 50S subunit khi thiab GTP yog hydrolyzed. Qhov no pib complex yog ib qho ua tiav ribosome uas muaj fMet tRNA hauv P site, ua raws li AUG codon ntawm mRNA, thiab ribosomal A site npaj tau txais qhov thib ob aminoacyl-tRNA.
Ib yam li ntawd, qhov kev pib pib ua dab tsi? Lo lus tseem ceeb - Initiation factor (KW-0396) Protein uas ua lub luag haujlwm tseem ceeb hauv kev pib kev txhais lus ntawm mRNA molecule rau hauv polypeptide. Pib yam tseem ceeb pab tsim cov complex ntawm mRNA thiab ribosome.
Yog li ntawd, dab tsi qhov chaw ua lub transcription pib complex?
Kev sau ntawv Factor proteins thiab RNA polymerase.
Yuav ua li cas molecules yuav tsum tau rau tsim ib tug txhais lus pib complex?
Kev txhais lus nyob rau hauv cov kab mob pib nrog cov tsim ntawm pib complex , uas suav nrog me me ribosomal subunit, mRNA, tus pib tRNA nqa N-formyl-methionine, thiab pib yam. Tom qab ntawd 50S subunit khi, tsim ib qho ribosome tsis zoo.

Dab tsi yog qhov transcription pib complex?
Transcription / DNA transcription. Ua ke, cov txheej txheem kev hloov pauv thiab RNA polymerase tsim ib txoj hauv kev hu ua transcription pib complex. Qhov nyuaj no pib sau cov ntaub ntawv, thiab RNA polymerase pib mRNA synthesis los ntawm kev sib piv cov hauv paus ntxiv rau cov thawj DNA strand
Dab tsi cuam tshuam rau kev tshem cov choj ntsev muaj rau kev ua haujlwm ntawm txhua lub xov tooj ntawm tes electrochemical?
Yog tsis muaj ntsev choj, cov tshuaj nyob rau hauv lub anode compartment yuav ua tau zoo them thiab cov tshuaj nyob rau hauv lub cathode compartment yuav ua tsis zoo nqi, vim hais tias ntawm tus nqi imbalance, lub electrode cov tshuaj tiv thaiv yuav sai sai los mus rau ib tug nres, yog li ntawd nws yuav pab kom tswj tau qhov khiav. los ntawm electrons
Dab tsi yog lub hauv paus rau kev txiav txim rau kev ua haujlwm ntawm cov hlau?
Cov kev ua si series yog ib daim ntawv teev cov hlau thiab lawv ib nrab-reactions nyob rau hauv thiaj li yuav txo tau yooj yim ntawm oxidation los yog ua kom muaj peev xwm coj ib tug electron
Cov txheej txheem dab tsi yog lub luag haujlwm rau txoj haujlwm ua haujlwm sib txawv?
Position-effect variegation (PEV) tshwm sim thaum cov noob ib txwm nyob hauv euchromatin yog sib xyaw nrog heterochromatin los ntawm kev hloov kho lossis hloov pauv. Thaum lub ntim ntim heterochromatin kis thoob plaws heterochromatin / euchromatin ciam teb, nws ua rau kev hloov pauv ntawm kev ntsiag to hauv tus qauv stochastic
Dab tsi yog qhov ua haujlwm ntawm Tfiih hauv qhov kev hloov pauv pib ua haujlwm?
(NER)TFIIH yog qhov kev hloov pauv dav dav uas ua haujlwm los nrhiav RNA Pol II rau cov neeg txhawb nqa ntawm cov noob. Nws ua haujlwm raws li lub helicase uas unwinds DNA. Nws kuj tseem tshem tawm DNA tom qab qhov mob DNA tau lees paub los ntawm txoj kev kho genome thoob ntiaj teb (GGR) lossis txoj kev hloov pauv-coupled kho (TCR) txoj hauv kev ntawm NER
