Bare tRNAs raug tso tawm rov qab rau hauv cytoplasm, qhov twg lawv tau rov qab siv dua tom qab raug "dhau" nrog cov amino acid tshiab.
TRNA puas siv tau ntau dua ib zaug?
Muaj ib txwm muaj ib qho aminoacyl tRNA synthetase rau txhua cov amino acid, txawm tias qhov tseeb tias tuaj yeem muaj ntau tshaj ib tRNA, thiab ntau tshaj ib qho tshuaj tiv thaiv rau cov amino acid.
tRNA siv theem twg?
Initiation ("pib"): nyob rau theem no, lub ribosome tau ua ke nrog mRNA thiab thawj tRNA thiaj li pib txhais lus. Elongation ("nrab"): nyob rau theem no, cov amino acids raug coj mus rau ribosome los ntawm tRNAs thiab txuas ua ke los tsim ib txoj saw.
Puas yog tRNA rov ua dua los ntawm ribosome?
Lub ribosome yog sab laug nrog mRNA thiab deacylated tRNAs hauv P thiab E qhov chaw. Hauv cov kab mob, posttermination 70S ribosome complexes tau rov ua dua los ntawm kev sib koom ua ke ntawm RRF thiab EF-G 1 … Cov qauv ntawm RRF khi rau ribosome muaj, Txawm li cas los xij, ua tsis tiav los piav qhia lub luag haujlwm ntawm tRNA thaum lub sij hawm ribosome splitting.
Puas yog tRNA siv rau hauv kev qhia noob?
Thaum raug kev txom nyem los ntawm qee yam kev ntxhov siab, tRNAs hloov qib ntawm aminoacylation los ua uncharged, thiab cov tRNAs tsis tau them nqi ua cov tshuaj molecules los tswj lub ntiaj teb cov noob qhia, kom cov kev ntxhov siab. Lub cev tiv thaiv kev ntxhov siab ib puag ncig.

Yuav tsum tau siv hluav taws xob siv dua?
Kev rov ua dua cov pov tseg los ntawm cov khoom siv hluav taws xob txuag chaw hauv cov chaw pov tseg thiab tiv thaiv ib puag ncig cov pa phem los ntawm cov co toxins. Kev rov ua dua tshiab kuj tseem txo qhov kev xav tau ntawm qhov chaw pov tseg hauv thawj qhov chaw.
Puas siv phau ntawv ntse siv rau ntawm cov khoom siv promethean?
Koj tuaj yeem tsim cov haujlwm uas siv LAB thiab lawv yuav ua haujlwm zoo ib yam thaum siv lub rooj tsavxwm Promethean. … Raws li koj tab tom siv Phau Ntawv Teev Npe ntawm Promethean lub rooj tsavxwm, cov haujlwm LAB yuav ua haujlwm tau zoo thiab sib tham sib .
Rau siv hauv ib hom fiber ntau yog siv zoo dua?
Rau siv hauv ib hom fiber ntau _ yog siv zoo dua. Nqe lus piav qhia: Semiconductor optical amplifiers muaj lub zog siv tsawg. Muaj ib hom qauv ua rau lawv tsim nyog thiab haum rau siv nyob rau hauv ib hom fiber ntau . Dab tsi yog daim ntawv thov ntawm optical amplifier?
Thaum twg yog qhov zoo dua rov qab siv dua?
Trench nrog recharge zoo Cov tswv yim no yog qhov tsim nyog rau thaj tsam qhov twg lub qab ntug permeable nyob hauv 3m hauv qab theem av. Recharge qhov dej ntawm 100-300 txoj kab uas hla yog tsim rau qhov tob ntawm yam tsawg 3 mus rau 5 m hauv qab dej .
Puas siab dua lossis qis dua bitrate zoo dua?
A tus nqi siab dua feem ntau txhais tau hais tias lub suab zoo dua"Bitrate yuav txiav txim siab lub suab ncaj ncees," hais tias tus tsim khoom thiab tus kws tshaj lij Gus Berry. "Koj tuaj yeem muaj lub suab kaw zoo tshaj plaws ntawm txhua lub sijhawm, tab sis yog tias koj ua si nrog tus nqi qis, nws yuav ua suab tsis zoo rau lwm qhov kawg.
