Thaum lub ribosome mus txog qhov nres codon, nws poob ntawm mRNA, thiab cov protein ua tiavMuaj peb qhov kev hloov pauv ntawm qhov nres codon: UGA, UAA, thiab UAG. Ntu ntawm mRNA ua ntej qhov pib no tsis tau txhais thiab paub tias yog 5′ cheeb tsam tsis tau txhais (5′ UTR) (Fig.
Yuav ua li cas thaum lub ribosome mus txog qhov nres codon?
Kawg, termination tshwm sim thaum lub ribosome ncav cuag qhov nres codon (UAA, UAG, thiab UGA). Txij li tsis muaj tRNA molecules uas tuaj yeem paub cov codons no, ribosome lees paub tias kev txhais lus tiav. Cov protein tshiab tau raug tso tawm, thiab cov kev txhais lus sib txawv tuaj.
Yuav ua li cas thaum nres codon mus txog?
A termination tRNAter khi rau codon thiab cov peptide loj hlob mus rau nws . Thaum peptidyl-tRNAter mus txog P site, lub ribosome tau taw qhia kom tso cov protein. Lub ribosome ces zoo li yuav dissociate.
Thaum tus ribosome nyeem qhov nres codon tus?
lub ribosome nyeem ib qho nres codon, cov saw hlau polypeptide yuav raug tso tawm rau hauv cytoplasm. 2 lub subunits ntawm ribosome poob sib nrug thiab mRNA raug tso tawm.
Yuav ua li cas thaum lub ribosome mus txog qhov nres codon quizlet?
Ib zaug ib lub ribosome mus txog qhov nres codon, txiav tawm tshwm sim thiab cov ribosomal subunits tawg tawm ntawm mRNA. Thaum muaj, nws yuav txuam nrog ribosomes, tsim tawm ntawm kev pib thiab protein.
