Cov nucleotides no yog ua tiav - lawv cov duab tso cai rau lawv daim ntawv cog lus ua ke nrog hydrogen bonds. Hauv C-G khub, tus tshuaj purine (guanine) muaj peb qhov chaw sib khi, thiab lwm yam ua tus pyrimidine (cytosine). Cov hydrogen kev sib raug zoo ntawm complementary bases yog dab tsi tuav ob strands ntawm DNA ua ke.

Ib yam li ntawd, koj tuaj yeem nug, hom ntawv cog lus twg ua purines thiab pyrimidines?

Purines ib txwm daim ntawv cog lus nrog pyrimidines ua ntawm hydrogen daim ntawv cog lus ua raws li txoj cai Chargaff hauv dsDNA, tshwj xeeb tshaj yog txhua tus daim ntawv cog lus ua raws li Watson-Crick hauv paus kev sib koom ua ke. Yog li ntawd, adenine tshwj xeeb daim ntawv cog lus rau thymine tsim ob hydrogen daim ntawv cog lus , yog guanine daim ntawv peb hydrogen daim ntawv cog lus Nrog Cytosine.

Tsis tas li ntawd, vim li cas purines ua ke nrog pyrimidines quizlet? Cov cov purines yog loj nyob rau hauv cov qauv thiab cov pyrimidines ua yog me me hauv cov qauv. Vim li cas ua koj xav tias purines daim ntawv cog lus nrog pyrimidines hauv DNA ntaiv? Ib txhia khub (Adenine thiab Thymine; Cytosine thiab Guanine) muaj tib tus lej ntawm hydrogen bonds.

Ua raws li qhov no saib, puas pyrimidines tsim cov ntawv cog lus nrog purines?

Pyrimidines daim ntawv Hydrogen Bonds Nrog Purines . Pyrimidines tsim Covalent Bonds nrog Purines . E. Adenine Thiab Guanine Yog Pyrimidines 2.)

Dab tsi yog purines thiab pyrimidines hauv DNA?

Purines thiab Pyrimidines yog nitrogenous bases uas ua rau ob yam sib txawv ntawm nucleotide bases nyob rau 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.
