GGG yog ib lub sij hawm coined los ntawm kev sib deev columnist Dan Savage los sawv cev rau cov zoo uas nws xav tias ua rau ib tug zoo kev sib deev khub. GGG stands rau "zoo, muab, thiab kev ua si." Xav tias "zoo hauv txaj," "muab sijhawm sib npaug thiab txaus siab sib npaug," thiab "kev ua si rau txhua yam-hauv qhov laj thawj."

Hauv qhov no, GGU code rau dab tsi?

Cov noob caj noob ces Code Properties Qhov no txhais tau tias txhua triplet codes rau tsuas yog ib qho amino acid. Lub degeneracy ntawm lub code rau cov amino acids coded los ntawm ob, peb, thiab plaub triplets tsuas yog nyob rau hauv lub hauv paus kawg ntawm lub triplet code . Piv txwv li, glycine yog coded los ntawm GGU , GGA, GGG, thiab GGC.

dab tsi yuav gag code rau? Kev hloov pauv. Kev hloov pauv yog qhov yuam kev hauv codons tshwm sim los ntawm kev hloov pauv hauv cov hauv paus nucleotide. Qee qhov kev hloov pauv muaj tsis muaj txiaj ntsig ntau. Piv txwv li, yog tias tus codon GAA dhau los ua tus codon GAG , vim gene code yog degenerate, lub codon yuav tseem code rau cov amino acid glutamate.

Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog txoj cai caj ces thiab nws siv rau dab tsi?

Cov kab mob caj ces yog cov txheej txheem uas siv los ntawm cov hlwb nyob los txhais cov ntaub ntawv hauv cov khoom siv caj ces (DNA lossis mRNA cov kab ke ntawm nucleotide triplets, lossis codons) rau hauv cov proteins.

Dab tsi yog 3 nres codons?

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).
