Ib qho kev xav tsis thoob tau ntsib thaum qhov sib lawv liag ntawm tib neeg mitochondrial DNA tau paub. Tib neeg mitochondria nyeem UGA li a codon rau tryptophan es tsis yog lub teeb liab nres (Table 5.5).

Hauv qhov no, dab tsi yog txoj cai caj ces rau tryptophan?

DNA codon rooj

AAG code rau dab tsi? Plaub lub hauv paus ua rau "cov ntawv" ntawm caj ces code . Cov ntawv yog ua ke nyob rau hauv pab pawg ntawm peb los ua code "lo lus," hu ua codons. Txhua codon stands rau (encodes) ib amino acid, tshwj tsis yog nws codes rau pib lossis nres teeb liab. Piv txwv li CUG codes rau leucine, AAG codes rau lysine, thiab GGG codes rau glycine.

Thiab cov lus nug yog, dab tsi yog codon rau phenylalanine?

Piv txwv li, cov amino acid phenylalanine (Ph) yog teev los ntawm tus codons UUU thiab UUC, thiab cov amino acid leucine (Leu) yog teev los ntawm cov codons CUU, CUC, CUA, and CUG.

Peb nres codons yog dab tsi?

Nres codons yog cov kab ke ntawm DNA thiab RNA uas yuav tsum tau ua nres txhais los yog ua cov proteins los ntawm stringing amino acids ua ke. Muaj peb RNA nres codons : UAG, UAA, and UGA. Hauv DNA, uracil (U) yog hloov los ntawm thymine (T).
