Nucleic acids yog macromolecules uas khaws cov ntaub ntawv caj ces thiab ua kom muaj protein ntau. Nucleic acids suav nrog DNA thiab RNA . Cov molecules no yog tsim los ntawm ntev strands ntawm nucleotides. Nucleotides yog tsim los ntawm nitrogenous puag, tsib-carbon qab zib, thiab ib pawg phosphate.
Tib neeg kuj nug, tus qauv ntawm nucleic acids yog dab tsi?
Basic Cov qauv ntawm Nucleic acids yog polynucleotides-uas yog, ntev chainlike molecules tsim los ntawm ib tug series ntawm ze li zoo tib yam lub tsev blocks hu ua nucleotides. Txhua nucleotide muaj cov nitrogen uas muaj cov ntxhiab tsw qab uas txuas nrog pentose (tsib-carbon) qab zib, uas yog nyob rau hauv lem txuas nrog phosphate pawg.
Qhov thib ob, peb lub luag haujlwm ntawm nucleic acids yog dab tsi? Ribonucleic acid (RNA) ua haujlwm hauv kev hloov cov ntaub ntawv caj ces los ntawm cov noob rau hauv cov amino acid sequences ntawm cov proteins . Peb hom universal RNA suav nrog hloov RNA (tRNA), tus xa xov RNA ( mRNA ), thiab ribosomal RNA (rRNA).
Ntawm no, lub luag haujlwm tseem ceeb ntawm nucleic acid yog dab tsi?
Cov muaj nuj nqi ntawm nucleic acids yuav tsum ua nrog kev khaws cia thiab kev nthuav qhia ntawm cov ntaub ntawv caj ces. Deoxyribonucleic kua qaub (DNA) encodes cov ntaub ntawv uas lub cell xav tau los ua cov proteins. Ib yam ntsig txog nucleic acid , hu ua ribonucleic kua qaub (RNA), los ntawm ntau hom molecular uas koom nrog cov protein synthesis.
Cov nucleic acids cais li cas?
Ob hom tseem ceeb ntawm nucleic acids yog DNA thiab RNA. Ob DNA thiab RNA yog tsim los ntawm nucleotides, txhua tus muaj tsib-carbon qab zib qaum, pawg phosphate, thiab nitrogen hauv paus.

Kev sib raug zoo ntawm cov qauv thiab kev ua haujlwm yog dab tsi?
Hauv biology, lub tswv yim tseem ceeb yog cov qauv txiav txim siab ua haujlwm. Hauv lwm lo lus, txoj kev npaj ib yam dab tsi ua rau nws ua nws lub luag haujlwm, ua tiav nws txoj haujlwm, hauv lub cev (ib yam khoom muaj sia). Cov qauv-kev sib raug zoo tshwm sim los ntawm cov txheej txheem ntawm kev xaiv ntuj
Dab tsi yog qee qhov haujlwm ntawm nucleic acids?
Lub luag haujlwm ntawm nucleic acids yuav tsum ua nrog kev khaws cia thiab nthuav tawm cov ntaub ntawv ntawm caj ces. Deoxyribonucleic acid (DNA) encodes cov ntaub ntawv uas lub cell xav tau los ua cov proteins. Ib hom nucleic acid, hu ua ribonucleic acid (RNA), tuaj nyob rau hauv ntau hom molecular uas koom nrog cov protein synthesis
Qhov kev sib raug zoo ntawm cov qauv thiab kev ua haujlwm quizlet yog dab tsi?
Cov qauv ntawm cov qauv txiav txim siab nws txoj haujlwm. Piv txwv li, yog tias cov duab ntawm cov protein hloov pauv, nws tsis tuaj yeem ua nws txoj haujlwm. Cov proteins uas yog cov enzymes muaj cov duab tshwj xeeb, zoo li tus yuam sij rau lub qhov rooj
Lub luag haujlwm ntawm nucleic acids hauv cov nroj tsuag yog dab tsi?
Lub luag haujlwm ntawm Nucleic Acids nyob rau hauv Dab Tsi? Nucleic acids yog cov molecules loj uas nqa tons ntawm cov ntsiab lus me me: tag nrho cov ntaub ntawv caj ces. Nucleic acids muaj nyob hauv txhua yam muaj sia - nroj tsuag, tsiaj txhu, kab mob, kab mob, fungi - uas siv thiab hloov lub zog
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
