DNA yog cov nucleic acid uas khaws cov ntaub ntawv ntawm caj ces. … Nucleotides tau koom ua ke los tsim cov nucleic acids los ntawm phosphate pawg ntawm ib nucleotide txuashauv kev sib txuas ester rau OH pawg ntawm peb cov pa roj carbon atom ntawm chav tsev qab zib ntawm nucleotide thib ob.

YPuas nucleotides tsim cov nucleic acids?

Nucleotides yog cov units thiab cov tshuaj uas sib koom ua ke ua nucleic acids, tshwj xeeb tshaj yog RNA thiab DNA.

Nucleic acids tsim li cas?

Nucleic acids yog tsim thaum nucleotides tuaj ua ke los ntawm phosphodiester linkages ntawm 5' thiab 3' carbon atoms. … Lawv yog tsim los ntawm monomers, uas yog nucleotides ua los ntawm peb yam: ib tug 5-carbon qab zib, ib pawg phosphate thiab ib tug nitrogenous puag.

Nucleotides dab tsi khi rau tsim nucleic acids?

Thaum nucleotides txuas mus rau DNA lossis RNA, phosphate ntawm ib nucleotide txuasntawm phosphodiester daim ntawv cog lus rau 3-carbon ntawm qab zib ntawm nucleotide tom ntej, tsim cov suab thaj. -phosphate caj qaum ntawm nucleic acid.
