DNA muaj cov suab thaj deoxyribose, thaum RNA muaj cov piam thaj ribose. Lub xwb qhov sib txawv ntawm ribose thiab deoxyribose yog tias ribose muaj ib pawg -OH ntau dua li deoxyribose, uas muaj -H txuas rau qhov thib ob (2') carbon hauv nplhaib. DNA yog ob-stranded molecule, thaum RNA yog ib leeg-stranded molecule.

Ib yam li ntawd, tib neeg nug, peb qhov sib txawv ntawm DNA thiab RNA yog dab tsi?

DNA yog ob-stranded, thaum RNA yog ib leeg-stranded. RNA muaj ribose li qab zib, thaum DNA muaj deoxyribose. Tsis tas li ntawd, peb ntawm cov nitrogenous hauv paus yog tib yam hauv ob hom (adenine, cytosine, thiab guanine), tab sis DNA muaj thymine thaum RNA muaj uracil.

Dab tsi yog qhov txawv ntawm DNA thiab RNA quizlet? Zoo li DNA , RNA yog tsim los ntawm 5-carbon surgar, ib pawg phosphate, thiab nitrogenous puag. RNA yog txawv los ntawm DNA yog peb txoj kev: (1) qab zib hauv RNA yog ribose tsis dioxyribose; (2) RNA feem ntau yog ib leeg-stranded thiab tsis yog ob-stranded; thiab (3) RNA muaj uracil nyob rau hauv qhov chaw ntawm thymine.

Hais txog qhov no, 4 qhov sib txawv tseem ceeb ntawm DNA thiab RNA yog dab tsi?

DNA yog ib tug ntev polymer nrog deoxyriboses thiab phosphate qaum. Muaj plaub sib txawv nitrogenous hauv paus: adenine, guanine, cytosine thiab thymine. RNA yog ib tug polymer nrog ib tug ribose thiab phosphate qaum. Plaub sib txawv nitrogenous bases: adenine, guanine, cytosine, thiab uracil.

Dab tsi yog ob qhov sib txawv ntawm DNA thiab RNA Brainly?

Teb yog: DNA thiab RNA txawv ntawm lawv cov qauv, kev ua haujlwm, thiab kev ruaj ntseg. DNA muaj plaub lub hauv paus nitrogen adenine, thymine, cytosine, thiab guanine thiab rau RNA es tsis txhob thymine, nws muaj uracil. Tsis tas li ntawd, DNA yog ob-stranded thiab RNA yog ib leeg-stranded uas yog vim li cas RNA tuaj yeem tawm ntawm lub nucleus thiab DNA ua tsis tau.
