tRNA hu ua adapter molecule vim nws txuas nws tus kheej los ntawm kev pib thiab elongation yam rau ribosome- mRNA complex uas pab txhawb kev koom ua ke ntawm cov amino acid kom raug rau cov saw hlau loj hlob. los ntawm nws cov anticodon tshwj xeeb rau mRNA codon.
TRNA hu ua tus adapter molecule yog dab tsi?
Transfer RNA (tRNA) yog luv luv nucleotide RNA saw. Nrog rau cov qauv L-shaped, tRNA ua haujlwm raws li 'adaptor' molecule uas txhais peb-nucleotide codon sib lawv liag hauv mRNA rau hauv cov amino acid uas tsim nyog ntawm codon.
Vim li cas tRNA hu ua adapter molecule kos nws cov qauv?
(b) tRNA A muaj lub voj anticodon uas muaj cov hauv paus ntxiv rau cov cai, thiab nws kuj muaj cov amino acid txais qhov kawg uas yog khi rau cov amino acids.… Txij li thaum, tib lub t-RNA molecule nyeem cov caj ces ntawm ib sab thiab khi rau ib qho tshwj xeebamino acid ntawm lwm tus, nws hu ua adapter molecule.
TRNA ua li cas los ua ib qho adapter molecule?
A kev hloov pauv RNA (cov ntawv luv tRNA thiab yav tas los hu ua sRNA, rau soluble RNA) yog ib qho adapter molecule uas muaj RNA, feem ntau 76 txog 90 nucleotides ntev (hauv eukaryotes), uas ua haujlwm raws li Kev sib txuas ntawm lub cev ntawm mRNA thiab cov amino acid sequence ntawm cov proteins.
Dab tsi yog qhov adapter molecule?
Adaptor molecules yog ntau cov proteins uas tsis muaj qhov ua haujlwm hauv cov catalytic, ua haujlwm hloov pauv los ntawm nucleating molecular complexes thaum lub teeb liab hloov pauv (53).
