A nucleotide yog lub tsev thaiv ntawm nucleic acids. RNA thiab DNA yog cov polymers ua los ntawm cov saw ntev ntawm nucleotides. Lub nucleotide muaj cov piam thaj molecule (xws li ribose hauv RNA lossis deoxyribose hauv DNA) txuas rau pawg phosphate thiab cov hauv paus muaj nitrogen.
Vim li cas nucleotides hu ua nucleic acids?
Lub sij hawm nucleic acid yog tag nrho lub npe rau DNA thiab RNA, cov tswv cuab ntawm tsev neeg ntawm biopolymers, thiab yog ib qho kev sib txuas nrog polynucleotide. Nucleic acids yog npe rau lawv qhov kev tshawb pom thawj zaug hauv lub nucleus, thiab rau qhov muaj cov phosphate pawg (txog rau phosphoric acid)
Nucleic acid ua nrog nucleotides yog dab tsi?
Ob hom nucleic acids yog DNA thiab RNAOb DNA thiab RNA yog tsim los ntawm nucleotides, txhua tus muaj tsib-carbon qab zib qaum, pawg phosphate, thiab nitrogen hauv paus. DNA muab cov cai rau cov haujlwm ntawm tes, thaum RNA hloov cov lej ntawd rau hauv cov protein kom ua haujlwm ntawm tes.
4 nucleic acids yog dab tsi?
Lub sijhawm xyoo 1920-45, ib txwm tshwm sim nucleic acid polymers (DNA thiab RNA) tau xav tias tsuas muaj plaub canonical nucleosides ( ribo-lossis deoxy-derivatives): adenosine, cytosine, guanosine, thiab uridine lossis thymidine.
Dab tsi yog 5 nucleic acids?
Muaj tsib qhov yooj yim 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 guanineTxawm koj nyob hauv chav kawm txuj ci twg, koj yuav hnov txog ATCG thaum saib DNA.
