Kev txhais tshwm sim hauv tus qauv hu ua ribosome , uas yog lub Hoobkas rau kev tsim cov proteins synthesis ntawm cov protein Protein biosynthesis (los yog protein synthesis) yog core biological txheej txheem, tshwm sim hauv cov hlwb, ntsuas qhov poob ntawm cov cellular proteins (ntawm degradation lossis export) los ntawm kev tsim cov proteins tshiab. … Qhov kev hloov dua siab tshiab no yog ua los ntawm cov enzymes, hu ua RNA polymerases, nyob rau hauv lub nucleus ntawm lub cell. https://en.wikipedia.org › wiki › Protein_biosynthesis
YProtein biosynthesis - Wikipedia
. Lub ribosome muaj ib tug me me thiab ib tug loj subunit thiab yog ib tug complex molecule tsim los ntawm ob peb ribosomal RNA molecules thiab ib tug xov tooj ntawm cov proteins.
Puas txhais lus tshwm sim hauv cytoplasm lossis ribosome?
Nyob rau hauv prokaryotes (cov kab mob thiab archaea), txhais tau tshwm sim hauv cytosol, qhov loj thiab me subunits ntawm ribosome khi rau mRNA. Hauv eukaryotes, kev txhais lus tshwm sim hauv cytoplasm lossis thoob plaws daim nyias nyias ntawm endoplasmic reticulum hauv cov txheej txheem hu ua co-translational translocation.
Kev txhais lus tshwm sim nyob qhov twg hauv txhua lub hlwb?
Nyob hauv eukaryotes, kev txhais lus thiab txhais lus muaj nyob rau hauv cov cellular compartments: transcription tshwm sim nyob rau hauv lub membrane-bounded nucleus, whereas translation tshwm sim sab nraum lub nucleus nyob rau hauv lub cytoplasm.
Kev txhais lus thiab kev txhais lus tshwm sim nyob qhov twg?
Lub eukaryoticnucleus yog li muab qhov sib txawv ntawm qhov sib txawv hauv lub xov tooj ntawm tes, tso cai rau kev hloov pauv thiab sib txuas ua ntej ua ntej pib kev txhais lus. Yog li, nyob rau hauv eukaryotes, thaum transcription tshwm sim nyob rau hauv lub nucleus, translation tshwm sim nyob rau hauv lub cytoplasm.
Yuav ua li cas thaum lub sijhawm txhais lus?
Yuav ua li cas thaum lub sijhawm txhais lus? Thaum lub sij hawm txhais lus, ribosome siv cov kab ke ntawm codons hauv mRNA los sib sau cov amino acids rau hauv cov saw hlau polypeptide. Qhov tseeb amino acids raug coj mus rau ribosome los ntawm tRNA. … Kev txiav txim siab ntawm mRNA cov lus rau hauv cov protein yog cov txheej txheem paub ua ob txoj haujlwm no.
