Cov haujlwm ntawm nucleic acids yuav tsum ua nrog tus khaws cia thiab nthuav qhia cov ntaub ntawv genetic. Deoxyribonucleic kua qaub (DNA) encodes tus cov ntaub ntawv tus cell yuav tsum tau ua cov protein. Ib yam ntsig txog nucleic acid , hu ua ribonucleic kua qaub (RNA), los ntawm ntau hom molecular uas koom nrog cov protein synthesis.

Hauv qhov no, 3 lub luag haujlwm tseem ceeb ntawm nucleic acids yog dab tsi?

Cov ntaub ntawv caj ces Lub luag haujlwm tseem ceeb ntawm DNA yog nqa cov cai rau kev ua cov proteins . Ib tug noob yog ib tug stretch ntawm DNA uas yuav nyeem tau los ntawm cov proteins hu ua ribosomes, thiab tau theej rau hauv ib hom nucleic acid hu ua messenger RNA (mRNA).

Tom qab, lo lus nug yog, dab tsi yog cov qauv thiab kev ua haujlwm ntawm nucleic acids? 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.

Ua raws li qhov xav tau, ob lub luag haujlwm tseem ceeb ntawm nucleic acid yog dab tsi?

Nucleic acids yog cov lub ntsiab cov ntaub ntawv nqa cov molecules ntawm tes, thiab, los ntawm kev coj cov txheej txheem ntawm cov protein synthesis, lawv txiav txim siab cov yam ntxwv ntawm txhua yam muaj sia nyob. Cov ob lub ntsiab chav kawm ntawm nucleic acids yog deoxyribonucleic kua qaub (DNA) thiab ribonucleic kua qaub (RNA).

Dab tsi yog cov ntsiab lus ntawm nucleic acids?

Cov pab pawg phosphate tso cai rau cov nucleotides sib txuas ua ke, tsim cov suab thaj-phosphate qaum ntawm nucleic acid thaum lub hauv paus nitrogenous muab cov tsiaj ntawv ntawm cov tsiaj ntawv caj ces. Cov Cheebtsam ntawm nucleic acids yog tsim los ntawm tsib lub ntsiab: carbon , hydrogen , oxygen , nitrogen , thiab phosphorus.
