Lub luag haujlwm ntawm Nucleic Acids yog dab tsi nyob rau hauv tej yam muaj sia? Nucleic acids yog cov molecules loj uas nqa tons ntawm cov ntsiab lus me me: tag nrho cov ntaub ntawv ntawm caj ces. Nucleic acids muaj nyob rau hauv txhua yam muaj sia nyob - nroj tsuag , tsiaj txhu, kab mob, kab mob, fungi - uas siv thiab hloov lub zog.

Tib neeg kuj nug, lub luag haujlwm ntawm nucleic acids 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.

Tsis tas li ntawd, cov nucleic acids nyob qhov twg hauv cov nroj tsuag? DNA hauv hlwb Hauv eukaryotes, xws li nroj tsuag thiab tsiaj, DNA yog pom nyob rau hauv lub nucleus, tshwj xeeb, membrane-bound vault nyob rau hauv lub cell , nrog rau qee yam ntawm lwm yam organelles (xws li mitochondria thiab chloroplasts ntawm nroj tsuag ).

Dhau li ntawm no, dab tsi yog 3 lub luag haujlwm tseem ceeb ntawm nucleic acids?

Cov ntsiab lus tseem ceeb: Nucleic acids Nucleic acids yog macromolecules uas khaws cov ntaub ntawv caj ces thiab pab tsim cov 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.

Dab tsi yog nucleic acids hauv biology?

Nucleic acids , uas yog tsim los ntawm nucleotides, yog cov loj heev thiab complex organic molecules uas muaj cov noob caj noob ces code rau lub cev. Ob hom kev sib raug zoo yog xav tau los xa cov ntaub ntawv caj ces los ntawm niam txiv mus rau cov xeeb ntxwv: DNA thiab RNA.
