Zuag qhia tag nrho Lub luag haujlwm ntawm tRNA hauv kev tsim cov protein yog txiav txim siab ib qho tshwj xeeb codon ntawm mRNA, siv nws cov anticodon, txhawm rau hloov cov amino acid tshwj xeeb mus rau qhov kawg ntawm cov saw hauv ribosome. Ntau tRNAs ua ke tsim los ntawm cov amino acid saw, thaum kawg tsim ib qho protein ntau rau tus thawj mRNA strand.
Dhau li ntawm qhov no, lub luag haujlwm ntawm tRNA yog dab tsi hauv cov lus nug ntawm cov protein synthesis?
Txhawm rau xa cov amino kom xa cov amino acids. Nqa cov amino acids thiab xa mus rau ribosome. tRNA xyuas kom meej cov amino acid raug xa tuaj ntawm lub sijhawm raug los ntawm kev sib piv cov tshuaj anticodons rau mRNA strands.
tRNA nyob qhov twg hauv protein synthesis? Cytoplasmic tRNAs muaj nyob rau hauv cov kua hauv cov hlwb (lub cytoplasm). Cov no tRNAs pab tsim cov proteins los ntawm cov noob nyob rau hauv DNA nyob rau hauv lub nucleus ntawm lub cell (nuclear DNA). Txawm hais tias feem ntau DNA yog nuclear, cellular qauv hu ua mitochondria muaj ib tug me me ntawm lawv tus kheej DNA, hu ua mitochondrial DNA.
Hauv qhov no, lub luag haujlwm ntawm tRNA yog dab tsi thaum lub sijhawm txhais lus?
hloov RNA / tRNA Hloov ribonucleic acid ( tRNA ) yog ib hom RNA molecule uas pab txiav txim siab tus tub txib RNA (mRNA) sib lawv liag rau hauv cov protein. tRNAs muaj nuj nqi ntawm qhov chaw tshwj xeeb hauv cov ribosome thaum lub sij hawm txhais lus , uas yog txheej txheem uas tsim cov protein los ntawm mRNA molecule.
Dab tsi yog lub luag haujlwm ntawm DNA thiab RNA hauv kev tsim cov protein?
DNA ua RNA ua Protein . Cov synthesis ntawm cov proteins tshwm sim nyob rau hauv ob theem ua ntu zus: Transcription thiab Translation. Transcription tshwm sim nyob rau hauv lub cell nucleus thiab siv lub hauv paus ib theem zuj zus ntawm DNA tsim mRNA. Lub mRNA nqa cov lus los ua ib qho tshwj xeeb protein ntau tawm mus rau cytoplasm qhov twg kev txhais lus tshwm sim.

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Koj xav li cas yog lub luag haujlwm ntawm RNA hauv kev tsim cov protein hauv cell?
Ribosomal RNA (rRNA) koom nrog cov txheej txheem ntawm cov protein los tsim ribosomes. Cov txheej txheem nyuaj no, uas lub cev txav mus raws ib qho mRNA molecule, catalyze lub sib dhos ntawm cov amino acids rau hauv cov protein chains. Lawv kuj khi tRNAs thiab ntau yam khoom siv molecules tsim nyog rau kev tsim cov protein
Dab tsi ntawm txoj kev tshawb fawb tuaj yeem txheeb xyuas hauv Darwin txoj haujlwm?
Kev xaiv ntuj thiab lwm yam txheej txheem ntawm kev hloov pauv tau raug tshawb xyuas los ntawm kev tsim thiab ntsuas cov kev xav. Darwin tau tshaj tawm cov kev xav hauv ntau qhov chaw, suav nrog geology, cog morphology thiab physiology, psychology, thiab evolution, thiab raug lawv mus rau qhov kev ntsuam xyuas loj heev
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
