lub luag haujlwm txhais lus

Txhua codon sawv rau ib qho tshwj xeeb amino acid , yog li yog cov lus hauv mRNA yog 900 nucleotides ntev, uas sib haum rau 300 codons, nws yuav muab txhais mus rau hauv ib tug saw ntawm 300 amino acids.

Ua li no, pes tsawg nucleotides nyob rau hauv ib qho amino acid?

peb nucleotides

Kuj Paub, muaj pes tsawg amino acids nyob rau hauv ib tug protein? 21 amino acids

Hais txog qhov no, pes tsawg codons yog 50 amino acids?

Peb paub tias, txhua tus amino acid yog tsim los ntawm triple codon . Yog li ntawd, yuav muaj tsawg kawg yog 150 codons rau 50 amino acids . Cistron yog ib feem ntawm mRNA uas codes rau ib qho tshwj xeeb amino acids suav nrog kev pib codon thiab nres codon . Tsis tas li ntawd yuav muaj 3 nucleotide cistron pib codon thiab nres codon txhua.

Dab tsi yog peb nucleotides ua ke hu ua mRNA?

Ib tug series ntawm codons nyob rau hauv ib feem ntawm ib tug tub txib RNA (mRNA) cov tshuaj molecule. Txhua codon muaj peb lub nucleotides, feem ntau sib raug rau ib qho amino acid. Cov nucleotides yog luv nrog cov ntawv A, U, G thiab C. Qhov no yog mRNA, uas siv U ( ua uracil ).
