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 tseem ua lub zog rau cov tshuaj tiv thaiv cellular thiab koom nrog hauv kev taw qhia.

Yog li ntawd, vim li cas nucleotide triphosphates siv hauv DNA synthesis?

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.

Ib sab saum toj no, puas yog ATP ribonucleoside triphosphate? ribonucleoside triphosphate . (NTP) ib qho ntawm plaub RNA precursor compounds ATP , CTP, GTP, thiab UTP.

Ib yam li ntawd, koj tuaj yeem nug, yog ATP yog dNTP?

. Qhov txawv ntawm ATP thiab deoxinucleoside triphosphate ( dNTP ) yog A. dNTP muaj suab thaj deoxyribose; ATP muaj qab zib ribose. dNTP muaj 2 pawg phosphate thaum ATP muaj 3 pawg phosphate.

Dab tsi yog qhov txawv ntawm nucleotide thiab nucleoside?

Nucleoside vs. Nucleotide . A nucleoside muaj ib tug nitrogenous puag covalently txuas mus rau ib tug qab zib (ribose los yog deoxyribose) tab sis tsis muaj phosphate pawg. A nucleotide muaj nitrogenous puag, qab zib (ribose los yog deoxyribose) thiab ib mus rau peb pawg phosphate.
