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.

Puas yog tus nplaig dov txuas ntxiv lossis tsis txuas ntxiv?
Tus nplaig dov yog ib qho piv txwv ntawm kev hloov pauv tsis tu ncua: koj tuaj yeem yob koj tus nplaig lossis koj ua tsis tau. Cov yam ntxwv uas qhia kev hloov pauv tas mus li feem ntau yog tshwm sim los ntawm txoj kev nyuaj, lossis ntau yam, cov qauv ntawm cov qub txeeg qub teg uas muaj ntau yam sib txawv ntawm cov noob thiab cov yam ntxwv hauv ib puag ncig (piv txwv li, kev noj haus)
Puas yog cov kab sib txuas ua pov thawj cov kab sib txuas?
Thawj yog yog tias cov ces kaum sib thooj, cov ces kaum uas nyob rau tib lub ces kaum ntawm txhua qhov kev sib tshuam, yog sib npaug, ces cov kab sib npaug. Qhov thib ob yog yog tias qhov sib txawv sab hauv lub kaum sab xis, cov ces kaum uas nyob rau sab nraud ntawm lub transversal thiab sab hauv cov kab sib npaug, sib npaug, ces cov kab sib npaug

Cov av qeeg loj tshaj plaws los ntawm qhov loj tshaj plaws Rank Hnub Magnitude 1 Tsib Hlis 22, 1960 9.4–9.6 2 Lub Peb Hlis 27, 1964 9.2 3 Kaum Ob Hlis 26, 2004 9.1–9.3 4 Lub Peb Hlis 11, 2011 9.1
Puas yog cov kab sib txuas sib txuas hauv hyperbolic geometry?
Hauv hyperbolic geometry, muaj ob hom kab sib npaug. Yog hais tias ob kab tsis sib tshuam nrog tus qauv ntawm hyperbolic geometry tab sis lawv sib tshuam ntawm nws tus ciam teb, ces cov kab yog hu ua asymptotically parallel lossis hyperparallel
