Messenger RNA (mRNA), molecule hauv cov hlwb uas nqa cov lej los ntawm DNA hauv cov nucleus mus rau qhov chaw ntawm cov protein synthesis hauv cytoplasm (cov ribosomes). Lub molecule uas nws thiaj li paub tias yog mRNA tau piav qhia thawj zaug hauv xyoo 1956 los ntawm cov kws tshawb fawb Elliot Volkin thiab Lazarus Astrachan.
Cov molecule twg tseem nyob hauv lub nucleus thaum lub sij hawm eukaryotic protein synthesis?
Cov molecule uas tseem nyob hauv lub nucleus thaum lub sij hawm tsim cov protein yog DNA DNA yog cov khoom siv caj ces ntawm tes thiab muaj tag nrho cov ntaub ntawv rau cov proteins uas lub cell xav tau. Thaum lub sij hawm thawj kauj ruam ntawm cov protein synthesis, hu ua transcription, DNA yog theej rau mRNA (messenger RNA).
Cov molecule twg dhau los ntawm cov nucleus mus rau cytoplasm thiab qhia txog qhov sib lawv liag ntawm cov amino acids hauv cov polypeptide tshiab?
Thaum lub sijhawm sib txuas ntawm cov protein hauv eukaryotes, cov molecule uas dhau los ntawm cov nucleus mus rau cytoplasm thiab qhia txog qhov sib lawv liag ntawm cov amino acids hauv cov polypeptide tshiab? the loj ribosomal subunit.
Yuav ua li cas molecules cuam tshuam ncaj qha nrog protein synthesis?
Nyob rau hauv lub ribosome, the rRNA molecules ncaj qha cov kauj ruam catalytic ntawm protein synthesis - lub stitching ua ke ntawm amino acids los ua ib tug protein molecule.
Yuav ua li cas thaum lub sij hawm tsim cov protein?
Protein synthesis yog txheej txheem uas cov hlwb ua cov protein. Nws tshwm sim hauv ob theem: transcription thiab translation … Kev txhais lus tshwm sim ntawm ribosome, uas muaj rRNA thiab cov proteins. Hauv kev txhais lus, cov lus qhia hauv mRNA raug nyeem, thiab tRNA coj qhov tseeb ntawm cov amino acids mus rau ribosome.
