Nitrogenous hauv paus muaj nyob hauv DNA tuaj yeem muab faib ua ob pawg: purines (Adenine (A) thiab Guanine (G)), thiab pyrimidine (Cytosine (C) thiab Thymine (T)). Cov nitrogenous hauv paus no txuas rau C1 'ntawm deoxyribose los ntawm glycosidic daim ntawv cog lus.
Cov khub twg yog purines?
Cov purines hauv DNA yog adenine thiab guanine, tib yam li hauv RNA. Cov pyrimidines hauv DNA yog cytosine thiab thymine; Hauv RNA, lawv yog cytosine thiab uracil. Purines loj dua pyrimidines vim tias lawv muaj ob lub nplhaib qauv thaum pyrimidines tsuas muaj ib lub nplhaib xwb.

Puas muaj pes tsawg lub hauv paus hauv purines?
Lub ob-carbon nitrogen ring bases (adenine thiab guanine) yog purines, hos ib-carbon nitrogen nplhaib bases (thymine thiab cytosine) yog pyrimidines.
Pyrimidine bases yog dab tsi?
YPyrimidines hauv DNA yog
C & T. Hauv RNA, U hloov T; thymine yog 5-methyl-uracil. Cov lej lej sib txawv hauv purine thiab pyrimidine rings, ua raws li cov cai los ntawm cov organic chemistry.
