Ib qho amino acid codon log (tseem hu ua cov xim amino acid lub log ) yog ib qho cuab yeej siv tau los nrhiav cov amino acid uas tau txhais los ntawm koj qhov RNA ib ntus. Codon lub log yog siv los ntawm cov kws tshawb fawb, cov kws tshawb fawb thiab cov tub ntxhais kawm thaum lub sij hawm RNA txhais lus los nrhiav cov amino acids rau qhov ua ntu zus raws li cov cuab yeej siv ceev, yooj yim siv.

Xav txog qhov no, koj siv lub log caj dab caj dab li cas?

Siv cov codon lub log txhais DNA codons rau hauv cov amino acids. Txhawm rau txiav txim siab lub codon nrhiav thawj tsab ntawv ntawm koj cov kab ke hauv lub voj voog sab hauv thiab ua haujlwm sab nraud kom pom cov amino acid sib raug. Piv txwv li: CAT cov lej rau H (Hisitidine). * Thov nco ntsoov qhov no lub log siv lub siab DNA codons (5' rau 3').

Ib sab saum toj no, yog N terminus 5 lossis 3? Thiab RNA yog ib txwm polymerized nyob rau hauv tsib prime mus rau peb lub ntsiab lus tseem ceeb. Tam sim no nrog peb cov amino acid, peb sau qhov kawg no, uas yog peb cov amino acid qhov kawg , as N thiab qhov kawg no yog peb cov carboxy qhov kawg raws li C.

Raws li txoj cai, muaj pes tsawg amino acids nyob rau ntawm lub log codon?

Nyob rau hauv cov cai no, txhua nucleotide hauv DNA lossis RNA molecule yuav code rau ib qho amino acid hauv protein. Tab sis txoj cai no tsis tuaj yeem ua haujlwm tau, vim tias muaj 20 20 2020 amino acids Feem ntau pom nyob rau hauv cov proteins thiab tsuas yog 4 4 44 nucleotide bases hauv DNA lossis RNA.

Lub codon code rau dab tsi?

caj ces code …ib unit hu ua codon , qho codes rau ib qho amino acid. Piv txwv li, cov kab ke AUG yog a codon uas qhia txog cov amino acid methionine. Muaj 64 qhov ua tau codons , peb cov ua tsis yog code rau amino acids tab sis qhia qhov kawg ntawm cov protein.
