DNA thiab RNA yog tsim los ntawm nucleotides uas txuas rau ib leeg hauv cov saw hlau los ntawm cov khoom siv tshuaj, hu ua ester bonds, nruab nrab ntawm cov piam thaj hauv ib nucleotide thiab pawg phosphate. ntawm cov nucleotide uas nyob ib sab.
DNA thiab RNA txuas li cas?
Ob leeg DNA thiab RNA yog tsim los ntawm nucleotides, txhua tus muaj tsib-carbon qab zib qaum, pawg phosphate, thiab nitrogen hauv paus. DNA muab cov cai rau cov haujlwm ntawm tes, thaum RNA hloov cov lej ntawd rau hauv cov protein kom ua haujlwm ntawm tes.
Dab tsi ntawm nucleotides koom ua ke hauv DNA thiab RNA?
Thaum nucleotides txuas rau daim DNA lossis RNA, phosphate ntawm ib nucleotide txuas ntawm 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.
Nucleotides koom ua ke li cas hauv Ib txoj hlua DNA yog qhov zoo ib yam rau RNA?
Nyob hauv ib lub xovtooj, ib lub nucleotide yuav muab ntxiv rau qhov kawg ntawm cov saw hlau polynucleotide yuav dais peb pawg phosphate. Thaum cov nucleotide koom nrog cov DNA loj hlob lossis RNA saw, nws poob ob pawg phosphate. Yog li, hauv cov saw hlau ntawm DNA lossis RNA, txhua nucleotide tsuas muaj ib pawg phosphate xwb.
Puas yog nucleotides koom ua ke los ntawm peptide bonds?
Peptide bonds yog tsim los ntawm pawg carboxylic acid ntawm ib cov amino acid thiab cov amino pawg ntawm ib thib obamino acid. … Nucleotides yog covalently txuas mus rau ib leeg los ntawm kev tsim ntawm phosphodiester bonds ntawm pawg suab thaj ntawm ib nucleotide thiab phosphate pawg ntawm nucleotide thib ob.
