Muaj ntau yam tshwm sim cov purines . Lawv suav nrog cov nucleobases adenine (2) thiab guanine (3). Hauv DNA, cov hauv paus no tsim cov ntawv cog lus hydrogen nrog lawv cov pyrimidines ntxiv, thymine thiab cytosine, feem. Hauv RNA, qhov sib ntxiv ntawm adenine yog uracil tsis yog thymine.

Ib yam li ntawd, guanine puas yog purine lossis pyrimidine?

Purines thiab Pyrimidines yog cov hauv paus nitrogenous uas ua rau ob yam sib txawv ntawm nucleotide hauv DNA thiab RNA. Ob-carbon nitrogen nplhaib hauv paus (adenine thiab guanine ) yog cov purines , thaum ib-carbon nitrogen nplhaib hauv paus (thymine thiab cytosine) yog pyrimidines ua.

uracil puas yog purine? Lwm hom hu ua a tshuaj purine . Uracil , lub hauv paus nitrogenous pom hauv RNA, yog pyrimidine. Ob lwm pyrimidines yog cytosine thiab thymine. Thymine tsuas pom muaj nyob hauv DNA.

Kuj tseem paub yog, vim li cas adenine thiab guanine hu ua purines?

Cov cov purines hauv DNA yog adenine thiab guanine , ib yam li hauv RNA. Cov pyrimidines hauv DNA yog cytosine thiab thymine; Hauv RNA, lawv yog cytosine thiab uracil. Purines yog loj dua pyrimidines vim hais tias lawv muaj ib tug ob-ntiv nplhaib qauv thaum pyrimidines tsuas muaj ib lub nplhaib.

Dab tsi yog purine molecule?

Purine yog ib qho heterocyclic aromatic organic compound, muaj ib lub nplhaib pyrimidine fused rau lub nplhaib imidazole. Ob lub hauv paus hauv nucleic acids, adenine thiab guanine, yog cov purines . Purines los ntawm cov zaub mov (los yog los ntawm cov ntaub so ntswg tig) yog metabolised los ntawm ob peb enzymes, xws li xanthine oxidase, rau hauv uric acid.
