Purine : Txhais
A tshuaj purine yog tsim los ntawm ib tug rau-tus tswv cuab nitrogen-muaj nplhaib thiab ib tug tsib-tus tswv cuab nitrogen-muaj nplhaib koom ua ke, zoo li ib tug hexagon thiab ib tug pentagon thawb ua ke. Purine cov hauv paus hauv DNA thiab RNA suav nrog adenine thiab guanine thiab yog li lub hauv paus paub zoo tshaj plaws ntawm qeb.
Hauv qhov no, lub ntsiab lus ntawm purine hauv biology yog dab tsi?
Kho mob Lub ntsiab lus ntawm Purine Purine : Ib qho ntawm ob chav kawm ntawm cov hauv paus hauv DNA thiab RNA. Cov tshuaj purine hauv paus yog guanine (G) thiab adenine (A). Uric acid, cov khoom ua txhaum cai hauv gout , yog a tshuaj purine khoom kawg.
Qhov thib ob, qhov ua haujlwm ntawm purine yog dab tsi? Ib qho tseem ceeb tshaj plaws luag hauj lwm purines pab yog nyob rau hauv kev tsim kho ntawm deoxyribonucleic acid (DNA) thiab ribonucleic acid (RNA). Ua khub cov purines thiab pyrimidines ua lub tsev blocks rau DNA.
Hauv qhov no, dab tsi yog purine hauv DNA?
Purines thiab Pyrimidines yog cov hauv paus nitrogenous uas ua rau ob yam sib txawv ntawm nucleotide hauv paus 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.
Ib qho piv txwv ntawm purine yog dab tsi?
Piv txwv ntawm cov purines xws li caffeine, xanthine, hypoxanthine, uric acid, theobromine, thiab nitrogenous bases adenine thiab guanine. Purines ua haujlwm zoo ib yam li pyrimidines hauv cov kab mob.

Dab tsi yog qhov txhais ntawm lub hauv paus hauv biology?
Txhais. npe, plural: bases. (1) (molecular biology) Lub nucleobase ntawm nucleotide koom nrog hauv kev sib koom ua ke, xws li DNA lossis RNA polymer. (2) (anatomy) Qhov qis tshaj plaws los yog hauv qab ntawm cov nroj tsuag lossis tsiaj lub cev ze tshaj rau qhov txuas. (3) (chemistry) Ib qho dej-soluble compound uas reacts nrog acid thiab cov ntaub ntawv
Dab tsi yog qeb yog marine biology nyob rau hauv?
Marine biology yog ib ceg ntawm biology. Nws muaj kev sib raug zoo nrog oceanography thiab tej zaum yuav raug suav hais tias yog ib qho kev ua haujlwm ntawm kev tshawb fawb hauv dej hiav txwv. Nws tseem suav nrog ntau lub tswv yim los ntawm ecology. Kev tshawb fawb txog kev nuv ntses thiab kev txuag dej hiav txwv tuaj yeem suav hais tias yog ib feem ntawm kev ua liaj ua teb marine biology (nrog rau kev tshawb fawb ib puag ncig)

Cov no yog cov feem ntau siv: resistors. Capacitors. LEDs. Transistors. Inductors. Integrated Circuits
Puas yog General Biology tib yam li cov hauv paus ntsiab lus ntawm biology?
Ob qho! Kuv xav tias nws nyob ntawm koj lub tsev kawm ntawv. Hauv kuv lub tsev kawm ntawv, cov ntsiab cai ntawm bio yog npaj rau bio majors, qhov dav dav bio yog rau lwm yam loj uas xav tau biology, uas yuav yooj yim dua
