Nucleic acids yog cov tseem ceeb tshaj plaws macromolecules rau lub neej txuas ntxiv. Lawv nqa cov kab mob ntawm cov kab mob ntawm tes thiab nqa cov lus qhia rau cov ua haujlwm ntawm lub cell. Ob lub ntsiab hom ntawm nucleic acids yog deoxyribonucleic kua qaub (DNA) thiab ribonucleic kua qaub ( RNA ).

Tsis tas li ntawd, 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.

Qhov thib ob, 2 hom nucleic acids yog dab tsi? Ob hom nucleic acids yog deoxyribonucleic acid (DNA) thiab ribonucleic acid (RNA). DNA yog cov noob caj noob ces khoom pom nyob rau hauv tag nrho cov kab mob nyob, xws li los ntawm ib leeg-celled kab mob mus rau multicellular mammals. Nws muaj nyob rau hauv lub nucleus ntawm eukaryotes thiab nyob rau hauv chloroplasts thiab mitochondria.

Kuj tseem paub yog, vim li cas nucleic acids tseem ceeb hauv lub cev ua haujlwm?

Lub luag haujlwm tseem ceeb ntawm nucleic acids yog khaws cov ntaub ntawv uas siv los ua cov protein. Nucleic acids tuaj nyob rau hauv ob lub ntsiab lus: deoxyribonucleic kua qaub , tseem hu ua DNA, thiab ribonucleic kua qaub , tseem hu ua RNA. Lub ntsiab muaj nuj nqi ntawm DNA yog khaws cov ntaub ntawv caj ces uas cov hlwb hauv lub lub cev xav tau muaj nuj nqi.

Dab tsi yog 3 lub luag haujlwm tseem ceeb ntawm nucleic acids?

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).
