Cov luag hauj lwm ntawm tRNA protein synthesis yog sib txuas nrog amino acids thiab hloov lawv mus rau ribosomes, qhov twg cov proteins tau sib sau ua ke raws li genetic code nqa los ntawm mRNA. Ib hom cov proteins hu ua enzymes catalyze biochemical tshua. Cov protein yog ua los ntawm ib ntu ntawm 20 amino acids.
Ib yam li ntawd, nws yog nug, dab tsi yog amino acids ua nyob rau hauv protein synthesis?
Amino acids , ntev suav hais tias tsuas yog substrates rau protein synthesis Tsis ntev los no tau pom tias ua raws li kev hloov pauv ntawm cov teeb liab intracellular transduction txoj kev feem ntau cuam tshuam nrog kev loj hlob-txhim kho cov tshuaj hormones xws li insulin thiab insulin zoo li kev loj hlob factor-1.
Kuj Paub, puas yog cov amino acids tsim thaum lub sij hawm tsim cov protein? Thaum ua ib protein ntau , lub ribosome tuav mRNA hauv qhov chaw. Thaum ib tug tRNA nkag mus rau hauv lub ribosome, nws khi rau ib qho ntxiv ntawm mRNA. Ntawm lub sijhawm no, tRNA tso nws amino acid yuav muab tso rau hauv ib txoj saw loj hlob ntawm amino acids uas yuav dhau los ua ib protein ntau.
Cov lus nug tseem yog, lub luag haujlwm ntawm cov amino acids hauv kev txhais lus yog dab tsi?
Amino acids ua kom tswj tau ntau yam txheej txheem ntsig txog gene qhia, nrog rau kev hloov pauv ntawm cov muaj nuj nqi ntawm cov proteins uas nruab nrab neeg xa xov RNA (mRNA) txhais lus.
Lub luag haujlwm ntawm protein synthesis yog dab tsi?
Protein synthesis yog cov txheej txheem tag nrho cov hlwb siv los ua cov protein, uas yog lub luag haujlwm rau tag nrho cov qauv ntawm tes thiab kev ua haujlwm. Muaj ob lub ntsiab lus tseem ceeb rau kev tsim cov protein. Hauv kev sau ntawv, DNA tau theej rau mRNA , uas yog siv los ua tus qauv rau cov lus qhia ua cov protein.

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
Lub luag haujlwm ntawm nucleic acids hauv cov nroj tsuag yog dab tsi?
Lub luag haujlwm ntawm Nucleic Acids nyob rau hauv Dab Tsi? Nucleic acids yog cov molecules loj uas nqa tons ntawm cov ntsiab lus me me: tag nrho cov ntaub ntawv caj ces. Nucleic acids muaj nyob hauv txhua yam muaj sia - nroj tsuag, tsiaj txhu, kab mob, kab mob, fungi - uas siv thiab hloov lub zog
Dab tsi yog qhov txawv ntawm Marine West Coast huab cua thiab dab tsi yog lub luag haujlwm rau cov yam ntxwv ntawd?
Cov ntsiab lus ntawm Marine West Coast Qhov kev nyab xeeb ntawm cov yam ntxwv tseem ceeb yog lub caij ntuj sov me me thiab lub caij ntuj no thiab cov nag lossis daus txhua xyoo. Qhov ecosystem no muaj kev cuam tshuam loj heev los ntawm nws qhov ze rau ntawm ntug dej hiav txwv thiab roob. Nws yog qee zaum hu ua huab cua sab hnub poob ntug dej hiav txwv lossis dej hiav txwv huab cua
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
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
