Nitrogenous bases tam sim no hauv DNA tuaj yeem muab faib ua ob pawg: purines (Adenine (A) thiab Guanine (G)), thiab pyrimidine (Cytosine (C) thiab Thymine (T)).
Puas adenine thiab guanine yog ob qho tib si 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.
Vim li cas adenine thiab guanine purines?
Lawv yog cov hauv paus nitrogenous uas ua rau ob lub nucleotides sib txawv hauv DNA thiab RNA. Purines (adenine thiab guanine) yog ob-carbon nitrogen ring bases hos pyrimidines (cytosine thiab thymine) yog ib-carbon nitrogen ring bases.
Puas adenine khub nrog purine?
A nrog T: cov purine adenine (A) ib txwm ua khub nrog pyrimidine thymine (T) C nrog G: pyrimidine cytosine (C) ib txwm ua khub nrog purine guanine (G)
Puas yog adenine thiab guanine hauv paus?
Base Pair
Txuas rau txhua lub suab thaj yog ib qho ntawm plaub lub hauv paus-- adenine (A), cytosine (C), guanine (G), lossis thymine (T).
