Kev sau ntawv. Transcription yog tus txheej txheem uas DNA yog theej (transcribed) rau mRNA, uas nqa cov ntaub ntawv xav tau rau protein synthesis . Kev hloov pauv yuav tshwm sim hauv ob kauj ruam dav. Ua ntej, tus xa xov xwm ua ntej RNA yog tsim, nrog kev koom tes ntawm RNA polymerase cov enzymes.
Ntxiv mus, DNA replication thiab protein synthesis yog dab tsi?
Protein synthesis thiab DNA replication yog ob tug mechanisms qhov twg ob-stranded DNA molecules muaj kev koom tes. thawj tus qauv. Protein synthesis yog cov synthesis ntawm ib qho amino acid sequence ntawm a protein ntau . DNA replication yog cov. synthesis ntawm ib qho tshiab DNA molecule los ntawm ib qho uas twb muaj lawm DNA molecule.
Tom qab ntawd, lo lus nug yog, dab tsi zoo sib xws hauv cov txheej txheem ntawm DNA replication thiab protein synthesis? Protein synthesis ua cov proteins , thaum DNA replication ua DNA . DNA replication tshwm sim nyob rau hauv lub nucleus thiab tsim ob zoo tib yam pawg DNA . Protein syntheses tsim mRNA, uas yog ces txhais los ntawm tRNA molecules nqa cov amino acids los tsim ib tug polypeptide los yog protein ntau.
Ntawm no, dab tsi yog replication nyob rau hauv protein synthesis?
Rov ua dua yog cov txheej txheem uas lub xovtooj ntawm tes ua ib daim qauv ntawm nws tus kheej DNA (copy DNA -> DNA). Rov ua dua tshwm sim nyob rau hauv S-fase nyob rau hauv kev npaj rau cell division thaum lub sij hawm cov ntaub ntawv genetic ntaub ntawv rau lub synthesis ntawm cov proteins yog hloov los ntawm mothercell mus rau lub daughtercell.
Dab tsi yog protein synthesis siv rau?
Protein synthesis yog cov txheej txheem tag nrho cov hlwb siv rau ua cov proteins , uas yog lub luag haujlwm rau tag nrho cov qauv ntawm tes thiab kev ua haujlwm. Muaj ob txoj hauv kev tseem ceeb rau protein synthesis . Hauv kev sau ntawv, DNA tau theej rau mRNA, uas yog siv li ib tug template rau cov lus qhia ua protein ntau.

Lub hauv paus dogma ntawm protein synthesis yog dab tsi?
Lub hauv paus dogma yog lub hauv paus ntsiab lus los piav qhia txog kev ntws ntawm cov ntaub ntawv caj ces los ntawm DNA rau RNA rau cov protein. Thaum cov amino acids koom ua ke los ua ib qho protein molecule, nws hu ua protein synthesis. Txhua cov protein muaj nws tus kheej cov lus qhia, uas yog encoded nyob rau hauv seem ntawm DNA, hu ua noob
Dab tsi yog qhov chaw ntawm cov protein synthesis hauv cell?
Protein yog sib sau ua ke hauv cov hlwb los ntawm ib qho organelle hu ua ribosome. Ribosomes muaj nyob rau hauv txhua hom cell loj thiab yog qhov chaw ntawm cov protein synthesis
Dab tsi yog lub luag haujlwm ntawm cov amino acids ua si hauv protein synthesis?
Lub luag haujlwm ntawm tRNA hauv kev sib txuas ntawm cov protein yog kev sib txuas nrog cov amino acids thiab hloov mus rau ribosomes, qhov twg cov proteins tau sib sau ua ke raws li genetic code nqa los ntawm mRNA. Ib hom proteins hu ua enzymes catalyze biochemical reactions. Proteins yog tsim los ntawm ib ntu ntawm 20 amino acids
Puas yog DNA thiab RNA koom nrog hauv cov txheej txheem ntawm cov protein synthesis quizlet?
Txheej txheem nyob rau hauv uas ib feem ntawm nucleotide ib theem zuj zus ntawm DNA yog theej mus rau hauv ib tug complementary sequence nyob rau hauv messenger RNA. Lub mRNA tuaj yeem tawm mus sab nraud ntawm lub nucleus thiab mus rau ribosomes. Cov txheej txheem uas cov ntaub ntawv genetic coded nyob rau hauv messenger RNA directs tsim ib tug tshwj xeeb protein ntawm ib tug ribosome nyob rau hauv lub cytoplasm
Thawj kauj ruam ntawm cov protein synthesis yog dab tsi thiab nws tshwm sim qhov twg?
Thawj kauj ruam ntawm protein synthesis hu ua Transcription. Nws tshwm sim nyob rau hauv lub nucleus. Thaum lub sijhawm sau ntawv, mRNA luam tawm (daim ntawv theej) DNA, DNA yog 'unzipped' thiab mRNA strand luam ib strand ntawm DNA. Thaum nws ua li no, mRNA tawm ntawm lub nucleus thiab nkag mus rau hauv cytoplasm, mRNA yuav txuas nws tus kheej mus rau ribosome
