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 cov ntsiab lus : carbon , hydrogen , oxygen , nitrogen , thiab phosphorus.
Tsis tas li ntawd, 4 hom nucleic acids yog dab tsi?
Basic qauv Txhua nucleic acid muaj plaub ntawm tsib lub hauv paus muaj nitrogen: adenine (A), guanine (G), cytosine (C), thymine (T), thiab uracil (U). A thiab G yog categorized li purines, thiab C, T, thiab U yog collectively hu ua pyrimidines.
Cov zaub mov twg muaj nucleic acids? Tsis tsuas yog cog cov nroj tsuag xws li cereals thiab pulses qhia cov ntsiab lus siab RNA sib npaug tab sis kuj zaub xws li spinach, leek, broccoli, Suav cabbage thiab cauliflower. Peb pom cov txiaj ntsig zoo ib yam hauv cov nceb suav nrog oyster, tiaj tus, khawm (whitecaps) thiab nceb nceb.
Kuj Paub, dab tsi yog lub tsev blocks ntawm nucleic acids?
Tag nrho cov nucleic acids yog tsim los ntawm tib lub tsev thaiv (monomers). Chemists hu cov monomers nucleotides ” Tsib daim yog uracil, cytosine, thymine, adenine, thiab guanine.
Nucleic acids ua haujlwm li cas?
Cov kev ua haujlwm 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.

Vim li cas nucleic acids tsis nyob rau hauv cov ntawv qhia zaub mov?
Txawm hais tias nucleic acids yog ib qho tseem ceeb macromolecule, lawv tsis nyob rau hauv cov zaub mov pyramid los yog ntawm cov khoom noj khoom haus. Qhov no yog vim lawv nyob rau hauv txhua yam peb noj uas ib zaug nyob thiab noj cov nyob los yog ib zaug muaj sia nyob tsis hloov ib yam ntawm peb genetic ntaub ntawv los yog tej zaum yuav pab tau los yog ua mob rau peb nyob rau hauv ib qho kev tshwm sim
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).
Dab tsi yog cov ions nyob rau hauv siab tshaj plaws concentration nyob rau hauv lub extracellular kua?
Cov tshuaj no nyob rau hauv cov kua dej extracellular thiab intracellular. Nyob rau hauv cov kua dej extracellular, cov cation loj yog sodium thiab cov anion loj yog chloride. Qhov loj cation nyob rau hauv cov kua dej intracellular yog poov tshuaj. Cov electrolytes no ua lub luag haujlwm tseem ceeb hauv kev tswj hwm homeostasis
Dab tsi yog nucleic acids siv rau hauv cov tsiaj muaj sia?
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)
Nyob rau hauv dab tsi organelle yog pyruvate oxidation nqa tawm nyob rau hauv ib lub cell?
Pyruvate oxidation cov kauj ruam Pyruvate yog tsim los ntawm glycolysis nyob rau hauv lub cytoplasm, tab sis pyruvate oxidation tshwm sim nyob rau hauv lub mitochondrial matrix (hauv eukaryotes). Yog li, ua ntej cov tshuaj tiv thaiv tuaj yeem pib, pyruvate yuav tsum nkag mus rau mitochondrion, hla nws daim nyias nyias thiab tuaj txog ntawm matrix
