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.
