Nucleic acids yog qhov tseem ceeb tshaj plaws macromolecules rau lub neej txuas ntxiv. Lawv nqa daim ntawv qhia txog caj ces ntawm lub xov tooj ntawm tes thiab nqa cov lus qhia rau kev ua haujlwm ntawm tes. Ob hom nucleic acids yog deoxyribonucleic acid ( DNA thiab ribonucleic acid ( RNA ).
Tsuas yog li ntawd, 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).
Ib sab saum toj no, lub luag haujlwm tseem ceeb ntawm nucleic acids hauv cov nroj tsuag yog 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 rau hauv txhua yam muaj sia nyob - nroj tsuag , tsiaj txhu, kab mob, kab mob, fungi - uas siv thiab hloov lub zog.
Yog li ntawd, ob lub luag haujlwm tseem ceeb ntawm nucleic acids 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 nucleic acids ua los ntawm?
Tag nrho nucleic acids yog ua los ntawm tib lub tsev blocks (monomers). Chemists hu cov monomers "nucleotides." Cov tsib daim yog uracil, cytosine, thymine, adenine, thiab guanine. Txawm hais tias koj nyob hauv chav kawm txuj ci dab tsi, koj yuav hnov txog ATCG thaum saib DNA. Uracil tsuas yog pom hauv RNA.

Dab tsi yog atoms nyob rau hauv 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 dab. Cov Cheebtsam ntawm nucleic acids yog tsim los ntawm tsib lub ntsiab: carbon, hydrogen, oxygen, nitrogen, thiab phosphorous
Muaj pes tsawg hom monomers muaj nyob rau hauv nucleic acids?
tsib Ntxiv mus, muaj pes tsawg hom monomers muaj nyob rau hauv cov hmoov txhuv nplej siab? Nyob ntawd tsuas yog 1. Ib yam li ntawd, qhov sib txawv ntawm nucleic acids yog dab tsi? Ob yam tseem ceeb ntawm nucleic acids yog deoxyribonucleic acid (DNA ) thiab ribonucleic acid (RNA).
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
Dab tsi ntawm cov hauv qab no muaj nyob rau hauv cov tsiaj hlwb tab sis tsis yog cov nroj tsuag?
Mitochondria, Cell Phab ntsa, Cell membrane, Chloroplast, Cytoplasm, Vacuole. Lub cell phab ntsa, chloroplasts thiab vacuole muaj nyob rau hauv cov nroj tsuag cell es tsis yog tsiaj hlwb
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
