Cycloheximide yog ib qho tshwm sim fungicide tsim los ntawm cov kab mob Streptomyces griseus. Cycloheximide exerts nws cov teebmeem los ntawm kev cuam tshuam nrog lub translocation kauj ruam nyob rau hauv protein synthesis (kev txav ntawm ob lub tRNA molecules thiab mRNA nyob rau hauv kev sib raug zoo rau lub ribosome), yog li thaiv eukaryotic translational elongation.
Ua raws li qhov xav tau, ua li cas Puromycin inhibit protein synthesis?
Puromycin yog ib qho tshuaj tua kab mob aminonucleoside, muab los ntawm Streptomyces alboniger kab mob, uas ua rau lub sij hawm luv luv ntawm cov saw hlau txiav thaum lub sij hawm kev txhais lus nyob rau hauv lub ribosome. Hauv cov tshuaj tiv thaiv no, a puromycin molecule yog chemically txuas mus rau qhov kawg ntawm mRNA template, uas yog ces muab txhais ua protein ntau.
Tsis tas li ntawd, chloramphenicol inhibits protein synthesis li cas? Lwm cov tshuaj tua kab mob, chloramphenicol , cuam tshuam nrog 50S subunit ntawm ribosome thiab tiv thaiv kev tsim ntawm peptide bonds. Cov macrolides, xws li erythromycin, yog xav tias inhibit protein synthesis los ntawm kev khi rau 50S subunit thiab thaiv lub qhov uas cov hlua polypeptide yog yuav tsum tawm.
Ib yam li ntawd, tib neeg nug, ua li cas cov protein synthesis inhibitors ua haujlwm?
A protein synthesis inhibitor yog ib yam khoom uas tso tseg lossis ua kom qeeb ntawm kev loj hlob lossis kev loj hlob ntawm cov hlwb los ntawm kev cuam tshuam cov txheej txheem uas coj ncaj qha mus rau tiam tshiab. cov proteins . Nws feem ntau yog hais txog cov tshuaj, xws li tshuaj tua kab mob, uas ua rau qib ribosome.
Vim li cas cycloheximide ntxiv rau qhov nruab nrab?
Sodium chloride yog ntxiv los tswj cov osmotic equilibrium. Agar yog tus neeg sawv cev solidifying. Qhov ntxiv ntawm cycloheximide ua rau nws xaiv nruab nrab inhibiting Saprophytic fungal kab mob uas tuaj yeem muaj nyob hauv cov qauv sib xyaw.

Vim li cas cov txheej txheem ntawm cov protein synthesis tseem ceeb rau lub neej?
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. Proteins tseem ceeb hauv txhua lub hlwb thiab ua haujlwm sib txawv, xws li koom nrog cov pa roj carbon dioxide rau hauv qab zib hauv cov nroj tsuag thiab tiv thaiv cov kab mob los ntawm cov tshuaj phem
DNA ncaj qha protein synthesis li cas?
Hom RNA uas muaj cov ntaub ntawv los ua cov protein hu ua messenger RNA (mRNA) vim nws nqa cov ntaub ntawv, lossis cov lus, los ntawm DNA tawm ntawm lub nucleus mus rau hauv cytoplasm. Los ntawm cov txheej txheem ntawm kev sau thiab txhais lus, cov ntaub ntawv los ntawm cov noob yog siv los ua cov protein
Yuav ua li cas protein synthesis?
Protein synthesis yog cov txheej txheem uas cov hlwb ua cov protein. Nws tshwm sim nyob rau hauv ob theem: transcription thiab translation. Kev hloov pauv yog hloov cov lus qhia caj ces hauv DNA mus rau mRNA hauv lub nucleus. Tom qab mRNA ua tiav, nws nqa cov lus qhia rau ribosome hauv cytoplasm
Yuav ua li cas unwinds DNA nyob rau hauv protein synthesis?
Kev sau ntawv. Kev hloov pauv yog cov txheej txheem uas DNA tau theej (tshaj tawm) rau mRNA, uas nqa cov ntaub ntawv xav tau rau kev tsim cov protein. Kev hloov pauv yuav tshwm sim hauv ob kauj ruam dav. Ua ntej, ua ntej tus tub txib RNA yog tsim, nrog rau kev koom tes ntawm RNA polymerase enzymes
Vim li cas txhua lub hlwb yuav tsum ua cov protein synthesis?
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. Lub ribosome, uas yog ib feem ntawm lub cell uas yuav tsum tau rau cov protein synthesis, qhia tRNA kom tau txais cov amino acids, uas yog lub tsev blocks ntawm proteins
