NTP yog siv hauv synthesis ntawm RNA primers thiab ATP yog siv raws li lub zog qhov chaw rau qee cov enzymes xav tau los pib thiab txhawb nqa DNA synthesis ntawm rov ua dua diav rawg. Cov nucleotide uas yog yuav tsum tau muab tso rau hauv kev loj hlob DNA saw yog xaiv los ntawm lub hauv paus khub nrog lub template strand ntawm lub DNA.
Ua li no, nucleoside triphosphates ua li cas?
Lawv yog lub tsev blocks ntawm DNA thiab RNA, uas yog chains ntawm nucleotides ua los ntawm cov txheej txheem ntawm DNA replication thiab transcription. Nucleoside triphosphates kuj yog ib qhov chaw ntawm lub zog rau cov tshuaj tiv thaiv cellular thiab yog koom nrog hauv kev taw qhia txoj hauv kev.
Ib yam li ntawd, nucleotides pab tau dab tsi rau? Hauv ob tsev neeg ntawm nucleic acids, ribonucleic acid (RNA) thiab deoxyribonucleic acid (DNA), qhov sib lawv liag ntawm nucleotides nyob rau hauv DNA lossis RNA cov lej rau cov qauv ntawm cov proteins uas tsim los hauv lub cell. Ob peb nucleotides yog coenzymes; Lawv ua nrog enzymes kom ceev (catalyze) biochemical cov tshuaj tiv thaiv.
Tom qab ntawd, ib tug kuj yuav nug, vim li cas DNA synthesis tseem ceeb?
DNA replication yog tseem ceeb txij li thaum nws tsim ib daim qauv tom ntej ntawm DNA uas yuav tsum tau mus rau hauv ib qho ntawm ob lub cell thaum lub cell faib. Tsis muaj rov ua dua , txhua lub xovtooj ntawm tes tsis muaj cov ntaub qhwv caj dab txaus los muab cov lus qhia tsim cov proteins tseem ceeb rau lub cev.
Dab tsi yog nucleic acid synthesis?
Nucleic acid metabolism yog cov txheej txheem uas nucleic acids ( DNA thiab RNA). synthesized thiab degraded. Nucleic acids yog cov polymers ntawm nucleotides. Nucleotide synthesis yog ib qho anabolic mechanism feem ntau koom nrog cov tshuaj tiv thaiv ntawm phosphate, pentose qab zib, thiab nitrogenous puag.

Vim li cas phosphate tseem ceeb hauv DNA?
Cov pab pawg phosphate tsuas yog cov phosphorus atom khi ua ke peb cov pa oxygen, tab sis nws muaj ntau lub luag haujlwm tseem ceeb. Ua ke nrog cov suab thaj thiab cov hauv paus, nws ua rau cov kua qaub nucleic, zoo li DNA thiab RNA
Tus neeg siv hauv zos siv li cas thaum ya mus rau IFR txoj hauv kev?
Tus neeg siv xov tooj cua xa mus rau 'chav kawm ua ntej' thiab 'rov qab kawm' los ntawm cov kav hlau txais xov. 'Chav kawm ua ntej' yog LOC kev qhia siv los ya tus txheej txheem ILS lossis LOC txoj hauv kev. Thaum cov txheej txheem ya mus los, tus neeg nyob hauv yog nyob ntawm qhov kawg ntawm txoj kev khiav koj tab tom tsaws
Vim li cas cov piam thaj siv hauv plasmid DNA cais tawm?
Lub hom phiaj ntawm cov kauj ruam no yog txhawm rau nce qhov pib ntim ntawm cov hlwb kom ntau plasmid DNA tuaj yeem raug cais tawm ib qho kev npaj. Glucose yog ntxiv los ua kom lub siab osmotic sab nraum lub hlwb. Tris yog tus neeg sawv cev buffering siv los tswj qhov pH tsis tu ncua (= 8.0)
Vim li cas pob zeb siv hauv cov hauv paus?
Cov tsev ua nrog cov pob zeb ua vaj tse, cov hauv paus, thiab cov plag tsev muaj zog heev vim tias lawv siv qhov zoo ntawm cov pob zeb uas muaj peev xwm nqus tau thiab khaws cov cua sov
Lub hauv paus ntsiab lus twg piav qhia tias vim li cas AFC poob qis thaum cov zis nce ntxiv cov ntsiab lus piav qhia vim li cas AVC nce ntxiv thaum cov zis nce ntxiv?
AFC poob qis vim qhov tso zis ntau ntxiv vim muaj kev sib kis. Tus nqi ruaj khov yog kis mus rau ntau dua thiab ntau dua units ntawm cov khoom tso tawm raws li cov zis ntau ntxiv. AVC nce raws li cov zis nce vim qhov txo qis rov qab los. Vim qhov txo qis rov qab mus rau kev ua haujlwm, nws raug nqi ntau dua los tsim txhua chav ntxiv ntawm cov zis
