Txawm hais tias thawj zaug pom nyob rau hauv lub nucleus ntawm eukaryotic hlwb, nucleic acids tam sim no paub tias muaj nyob rau hauv tag nrho cov hom ntawm lub neej, suav nrog nyob rau hauv cov kab mob, archaea, mitochondria, chloroplasts, thiab kab mob (Muaj kev sib cav txog seb cov kab mob puas nyob lossis tsis nyob).
Nucleic acids pom piv txwv nyob qhov twg?
Ob qho piv txwv ntawm nucleic acids suav nrog deoxyribonucleic acid (zoo dua hu ua DNA) thiab ribonucleic acid (zoo dua hu ua RNA). Cov molecules no yog tsim los ntawm ntev strands ntawm nucleotides tuav ua ke los ntawm covalent bonds. Nucleic acids tuaj yeem pom nyob rau hauv lub nucleus thiab cytoplasm ntawm peb cov hlwb
Nucleic acids pom zaub mov nyob qhov twg?
Tsis tsuas yog cog cov nroj tsuag xws li ua cov nplej thiab pulsesqhia cov ntsiab lus RNA siab sib npaug tab sis kuj muaj zaub xws li spinach, leek, zaub paj, zaub qhwv thiab zaub qhwv. Peb pom cov txiaj ntsig zoo ib yam hauv cov nceb suav nrog oyster, tiaj tus, khawm (whitecaps) thiab nceb nceb.
Nucleic acids xub pom qhov twg?
Nucleic acid tau tshawb pom nyob rau xyoo 1869 los ntawm Swiss biochemist Johann Friedrich Miescher (1844–1895), uas thawj zaug pom cov nplaum nplaum, ntshiab tshuaj nyob rau hauv lub nucleus ntawm hlwb Nws tis npe rau nws. nuclein, thiab txawm hais tias tom qab ntawd nws tau los ua lub npe hu ua nucleic acid, tsis muaj leej twg muaj lub tswv yim tias nws yog nyob rau hauv qee txoj kev txuas nrog kev xeeb tub.
Puas muaj nucleic acids nyob hauv tib neeg?
Tib neeg muaj ob hom nucleic acids hauv lawv lub cev: DNA thiab RNA. Cov molecules no muaj cov lus qhia rau peb lub hlwb: lawv txiav txim seb peb yog leej twg.

Puas yog cov ntsiab lus ntawm nucleic acids?
19.5. Nucleic acids yog cov loj heev biomolecules ua los ntawm monomers hu ua nucleotides. Nucleotides muaj peb yam: pentose qab zib (5-carbon qab zib), phosphate pawg, thiab nitrogenous puag . Nucleotide cov ntsiab lus yog dab tsi? Nucleotide A nucleotide muaj qab zib molecule (xws li ribose hauv RNA lossis deoxyribose hauv DNA) txuas rau pawg phosphate thiab cov hauv paus muaj nitrogen Cov hauv paus siv DNA yog adenine (A), cytosine (C), guanine (G), thiab thymin
Puas yog cov concentrated acids muaj zog acids?
A cov kua qaub uas muaj zog yog ib qho kev sib cais tag nrho los tsim H3O + ions hauv cov tshuaj aqueous, qhov twg raws li cov kua qaub tsis muaj zog tsuas yog ua qee yam. Cov kua qaub concentrated, ntawm qhov tod tes, yog ib qho uas muaj qhov siab heev ntawm H3O + ions hauv cov kua dej .
Cov ntsia liaj qhov rooj nyob rau hauv qhov phem 3 nyob qhov twg?
Tus Neeg Siab Phem 3 tus ntsia liaj qhov rooj tau pom nyob rau hauv chav me me tsis muaj npe txuas nrog lub Chaw nres tsheb hauv plawv nroog . Kuv puas yuav tsum muab cov ntsia hlau txiav Resident Evil 3? Koj tsis tuaj yeem pov tseg cov khoom koj xav tau rau lub hom phiaj, xws li lub xauv xauv lossis ntsia liaj qhov rooj.
Dab tsi yog qhov txawv ntawm kev pom tsis pom thiab pom tsis pom ntau dua?
Kev muaj peev xwm tawm tsam yam tsis muaj qhov kawg ntawm kev sau ntawv vs kev tuaj yeem cuam tshuam rau lwm tus neeg kuj yog qhov sib txawv. Qhov tseem ceeb Invisibility yog "qhov tseeb nrhiav / nkaum / mus ncig tsis pom" qhov twg Qhov Kev Pom Zoo Tshaj Plaws yog ntau ntawm kev sib ntaus sib tua Puas pom qhov tsis pom kev ua haujlwm ntawm kev pom tsis pom ntau dua?
Puas yog cov txhawb nqa los ntawm nucleic acids?
Cov neeg txhawb nqa yog ua los ntawm nucleic acids. Tus neeg txhawb nqa yog ib ntu ntawm DNA hauv paus uas yog nce mus txog qhov chaw pib ntawm cov noob . Puas yog txhawb nqa ntawm DNA lossis RNA? Promoter sequences yog DNA sequences uas txhais tau tias qhov twg transcription ntawm cov noob los ntawm RNA polymerase pib.
