Purines vs. Pyrimidines
| Purines | Pyrimidines | |
|---|---|---|
| Qauv | Ob chav carbon-nitrogen nplhaib nrog plaub nitrogen atoms | Ib lub nplhaib carbon-nitrogen nrog ob lub nitrogen atoms |
| Loj | Loj dua | Me me |
| Qhov chaw | Adenine thiab Guanine nyob rau hauv ob qho tib si DNA thiab RNA | Cytosine hauv ob qho tib si DNA thiab RNA Uracil tsuas yog hauv RNA Thymine nkaus xwb DNA |
Ib yam li ntawd, dab tsi lwm lub hauv paus yog ob lub nplhaib qauv?
Ib qho nucleotide yog tsim los ntawm ib qho qab zib molecule, ib qho phosphate molecule thiab ib qho ntawm plaub lub hauv paus. Ntawm no yog cov qauv qauv rau plaub nucleotides ntawm DNA. Nco ntsoov tias cov tshuaj purine hauv paus (adenine thiab guanine) muaj ob lub nplhaib qauv thaum lub pyrimidine hauv paus (thymine thiab cytosine) tsuas muaj ib lub nplhaib xwb.
Tsis tas li ntawd, ob lub hauv paus dab tsi hauv DNA molecule yog ob chav ringed quizlet? Lub tsib-carbon qab zib hauv a DNA nucleotide hu ua deoxyribose. Nitrogenous hauv paus uas muaj a ob lub nplhaib ntawm carbon thiab nitrogen atoms, xws li adenine thiab guanine, hu ua purines. Nitrogenous hauv paus uas muaj ib leeg nplhaib ntawm carbon thiab nitrogen atoms, xws li cytosine thiab thymine, hu ua pyrimidines.
Sib piv, dab tsi yog ob lub nplhaib nitrogenous puag?
Cov no nitrogenous bases yog adenine (A), uracil (U), guanine (G), thymine (T), thiab cytosine (C). Lawv muaj ib leeg nplhaib qauv. Purines muaj xws li adenine thiab guanine. Lawv muaj ib ob lub nplhaib qauv.
Lub nplhaib ib leeg yog dab tsi?
Pyrimidine hauv paus ( ib lub nplhaib qauv ) yog thymine, cytosine thiab uracil. Purine puag ( ob lub nplhaib qauv ) yog adenine thiab guanine.

Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
