Thaum lub sijhawm elongation, lub ribosome txuas ntxiv txhais txhua codon nyob rau hauv lem. Txhua tus sib raug zoo amino acid yog ntxiv rau cov saw loj hlob thiab txuas ntawm daim ntawv cog lus hu ua peptide daim ntawv cog lus. Elongation txuas ntxiv mus txog thaum tag nrho cov codons tau nyeem … Cov protein tshiab raug tso tawm, thiab cov kev txhais lus sib txawv tuaj.
Yuav ua li cas thaum txhais lus hauv ribosome?
Thaum lub sijhawm txhais lus, ribosomal subunits sib dhos ua ke zoo li lub qhaub cij ntawm mRNA strand ntawm mRNA, qhov chaw uas lawv pib nyiam tRNA molecules tethered rau cov amino acids (lub voj voog). Ib txoj kab ntev ntawm cov amino acids tshwm sim thaum lub ribosome txiav txim siab lub mRNA sib lawv liag mus rau hauv ib tug polypeptide, los yog ib tug tshiab protein.
Yuav ua li cas thaum lub sijhawm txhais lus?
Yuav ua li cas thaum lub sijhawm txhais lus? Thaum lub sij hawm txhais lus, a ribosome siv cov kab ke ntawm codons hauv mRNA los sib sau cov amino acids rau hauv cov saw polypeptideCov 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.
3 kauj ruam ntawm kev elongation ntawm kev txhais lus yog dab tsi?
Saib seb cov hlwb ua cov protein li cas, cia peb faib cov txhais ua peb theem: pib (pib tawm), elongation (ntxiv rau cov saw protein), thiab txiav tawm (ua tiav.).
Yuav ua li cas txhais cov kauj ruam ntawm kev txiav txim?
Muaj peb kauj ruam tseem ceeb rau kev txhais lus: Initiation, Elongation, and Termination.
