Nws txuas los ntawm ib kawg ntawm tRNA molecule . Nws yog lub hauv paus chav tsev ntawm cov noob caj noob ces. Nws muaj peb nucleotides. Nws yeej tsis code rau ntau tshaj ib amino acid.

Ua kom pom qhov no, dab tsi nyob rau hauv qhov kawg ntawm tRNA molecule?

Hauv 3' kawg ntawm tRNA molecule , tawm tsam cov tshuaj tiv thaiv, txuas ntxiv peb qhov chaw txais cov nucleotide uas suav nrog pawg dawb -OH. Ib qho tshwj xeeb tRNA khi rau ib qho tshwj xeeb amino acid los ntawm nws cov qia txais.

Tsis tas li ntawd, qhov twg yog qhov tseeb ntawm codon? Transcribed Image Text Nws muaj peb lub nucleotides Nws yog lub hauv paus chav tsev ntawm cov noob caj noob ces. Nws yuav code rau tib amino acid li lwm tus codon . Nws yeej tsis code rau ntau tshaj ib cov amino acid. Nws txuas los ntawm ib kawg ntawm tRNA molecule.

Khaws qhov no hauv kev xav, dab tsi yog qhov anticodon ntawm ib qho tRNA molecule?

Anticodon . Ib anticodon yog ib chav tsev tsim los ntawm peb lub nucleotides uas sib haum rau peb lub hauv paus ntawm codon ntawm mRNA. Txhua tRNA muaj qhov txawv anticodon triplet sequence uas tuaj yeem tsim 3 lub hauv paus ua ke rau ib lossis ntau codons rau cov amino acid.

Dab tsi yog 2 yam ntawm tRNA molecule?

Anticodon ntawm ib tug muab tRNA tuaj yeem khi rau ib lossis ob peb qhov tshwj xeeb mRNA codons. Cov tRNA molecule kuj yog ib qho amino acid: tshwj xeeb, ib qho encoded los ntawm codons uas tus tRNA khi. [5' thiab 3' txhais li cas?] Lub ob xaus ntawm ib txoj hlua DNA los yog RNA txawv ib leeg.
