Deoxyribose ua rau tus txha caj qaum ntawm DNA ob helix thaum ob molecules ntawm DNA khi ua ke. Cov nitrogenous hauv paus khi tshwj xeeb ntawm ob DNA molecules los tsim cov qauv ntawm DNA.

Tsis tas li cov lus nug yog, dab tsi ua rau tus txha caj qaum ntawm DNA?

Qauv ntawm DNA Nws muaj alternating tshuaj phosphate thiab qab zib qaum , ua 'sab' ntawm tus ntaiv. (Deoxyribose yog lub npe ntawm cov suab thaj muaj nyob hauv caj qaum DNA .) (Ib pawg zoo li no ntawm phosphate, qab zib, thiab lub hauv paus ua ib subunit DNA hu ua nucleotide.)

Ib sab saum toj no, phosphodiester bond quizlet yog dab tsi? A phosphodiester daim ntawv cog lus yog ib pab pawg muaj zog covalent daim ntawv cog lus nruab nrab ntawm ib pab pawg phosphate thiab ob 5-carbon nplhaib carbohydrates (pentoses) tshaj ob ester daim ntawv cog lus . (aka: cov suab thaj uas nyob ib sab txuas los ntawm covalent daim ntawv cog lus )

Yog li, dab tsi yog lub caj qaum ntawm DNA ua los ntawm quizlet?

Cov deoxyribose thiab phosphate pawg tsim cov qaum ntawm nucleic acid molecule.

DNA yog dab tsi?

DNA yog ua los ntawm chemical tsev blocks hu ua nucleotides. Cov tsev blocks no yog ua los ntawm peb ntu: ib pawg phosphate, ib pawg suab thaj thiab ib qho ntawm plaub hom nitrogen hauv paus. Ua ib txoj hlua ntawm DNA , nucleotides txuas rau hauv cov saw hlau, nrog cov phosphate thiab qab zib pawg hloov pauv.
