Kev daws 1 Yog li ntawd, ntawm hydrolysis ntawm DNA, qhov ntau ntawm adenine tsim yog sib npaug ntawm thymine thiab zoo ib yam, qhov ntau ntawm cytosine yog sib npaug ntawm guanine. Tab sis thaum RNA yog hydrolyzed, tsis muaj kev sib raug zoo ntawm qhov ntau ntawm cov hauv paus sib txawv tau txais. Li no, RNA yog ib leeg-stranded.
Thaum RNA yog hydrolyzed tsis muaj kev sib raug zoo ntawm qhov ntau ntawm cov hauv paus sib txawv tau txais qhov tseeb no qhia txog tus qauv ntawm RNA?
14.8 Thaum RNA yog hydrolysed, tsis muaj kev sib raug zoo ntawm qhov ntau ntawm cov hauv paus sib txawv tau txais. Qhov tseeb no qhia li cas txog tus qauv ntawm RNA? Thaum RNA yog hydrolysed, tsis muaj kev sib raug zoo ntawm qhov ntau ntawm cov hauv paus sib txawv tau txais, qhov tseeb no qhia tias RNA yog ib qho qauv sib txuas.
Yuav ua li cas thaum RNA yog hydrolysed?
RNA hydrolysis yog cov tshuaj tiv thaiv uas a phosphodiester daim ntawv cog lus hauv qab zib-phosphate qaum ntawm RNA tawg, cleaving RNA molecule. Cov yam ntxwv no ua rau RNA tshuaj tsis ruaj khov piv rau DNA, uas tsis muaj 2 '-OH pawg thiab yog li tsis raug rau hauv paus-catalyzed hydrolysis. …
Yuav ua li cas yog cov khoom hauv hydrolysis ntawm RNA?
Muab hais tias RNA yog tsim los ntawm plaub nucleotide monomers (piv txwv li, monophosphates ntawm adenosine, guanosine, cytidine, thiab uridine), muaj yim cov tshuaj tiv thaiv ntawm alkaline RNA hydrolysis (piv txwv li, 2ʹ- thiab3ʹ-isomers ntawm txhua ntawm plaub ribonucleotides).
Cov khoom lag luam twg yuav tsim thaum muaj nucleotide los ntawm DNA uas muaj thymine hydrolysed?
Thaum ib nucleotide los ntawm DNA uas muaj thymine yog hydrolyzed, cov khoom yog thymine β-D-2-deoxyribose thiab phosphoric acid.
