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.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
