transfer RNA / tRNA Proteins yog tsim los ntawm me me hu ua amino acids, uas tau teev los ntawm three-nucleotide mRNA sequences hu ua codons. Txhua codon sawv cev rau ib qho amino acid, thiab txhua codon raug lees paub los ntawm ib qho tshwj xeeb tRNA.
Yog codons ntawm mRNA?
Txhua pawg ntawm peb lub hauv paus hauv mRNA tsim ib codon, thiab txhua tus codon qhia txog cov amino acid tshwj xeeb (li no, nws yog triplet code). Lub mRNA ib ntus yog li siv los ua tus qauv los sib sau ua ke-hauv kev txiav txim-cov saw ntawm cov amino acids uas tsim cov protein. … Cov codons tau sau 5' txog 3', raws li lawv tshwm hauv mRNA.
Puas tRNA ua codons?
Txhua tRNA muaj ib pawg ntawm peb nucleotides hu ua anticodon. Cov tshuaj tiv thaiv ntawm ib qho tRNA tuaj yeem khi rau ib lossis ob peb qhov tshwj xeeb mRNA codons. Lub tRNA molecule kuj nqa ib qho amino acid: tshwj xeeb, ib qho encoded los ntawm codons uas tRNA khi.
Puas yog genetic code mRNA lossis tRNA?
Messenger RNA (mRNA) nqa cov ntaub ntawv caj ces theej los ntawm DNA hauv daim ntawv ntawm peb lub hauv paus code "cov lus," txhua yam uas qhia txog cov amino acid tshwj xeeb.. 2. Hloov RNA (tRNA) yog tus yuam sij rau deciphering cov lus code hauv mRNA.
Is tRNA antiparallel rau mRNA?
Ib anticodon yog peb lub hauv paus ib ntus, ua ke nrog cov amino acid tshwj xeeb, uas tRNA molecule coj mus rau qhov sib thooj codon ntawm mRNA thaum lub sijhawm txhais lus. Anticodon sequence yogcomplementary rau mRNA, siv lub hauv paus khub nyob rau hauv anti-parallel kev taw qhia.
