DNA yog ob-stranded molecule, thaum RNA yog ib leeg-stranded molecule. DNA yog ruaj khov nyob rau hauv alkaline tej yam kev mob, thaum RNA tsis ruaj khov. DNA thiab RNA base pairing yog me ntsis txawv txij li thaum DNA siv lub hauv paus adenine, thymine, cytosine, thiab guanine; RNA siv adenine, uracil, cytosine, thiab guanine.
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.
Tom qab ntawd, lo lus nug yog, qhov txawv ntawm DNA thiab RNA quizlet yog dab tsi? 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.
Raws li txoj cai, 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 5 qhov sib txawv ntawm DNA thiab RNA?
DNA muaj cov suab thaj deoxyribose, thaum RNA muaj cov piam thaj ribose. DNA thiab RNA base pairing yog txawv me ntsis txij li thaum DNA siv lub hauv paus adenine, thymine, cytosine, thiab guanine; RNA siv adenine, uracil, cytosine, thiab guanine. Uracil txawv ntawm thymine vim tias nws tsis muaj methyl pawg ntawm nws lub nplhaib.

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 peb qhov sib txawv ntawm DNA thiab RNA?
DNA yog ob-stranded, thaum RNA yog ib leeg-stranded. RNA muaj ribose ua suab thaj, thaum DNA muaj deoxyribose. Tsis tas li ntawd, peb lub hauv paus nitrogenous yog tib yam hauv ob hom (adenine, cytosine, thiab guanine), tab sis DNA muaj thymine thaum RNA muaj uracil
Vim li cas A thiab T thiab G thiab C ua khub hauv DNA ob lub helix?
Qhov no txhais tau hais tias txhua ntawm ob strandsindouble-stranded DNA ua raws li ib tug templatetoproduce ob strands tshiab. Replication relies oncomplementary basepairing, uas yog lub hauv paus ntsiab lus piav qhia los ntawmChargaff cov cai: adenine (A) ib txwm khi nrog thymine (T) thiab cytosine (C) ib txwm khi nrog guanine (G)
Vim li cas niam txiv thiab tus ntxhais hlwb hauv mitosis thiab meiosis txawv?
Kev piav qhia: Qhov sib txawv tseem ceeb ntawm mitosis thiab meiosis tshwm sim hauv meiosis theem I. Nyob rau hauv mitosis, tus ntxhais cell muaj tib tus naj npawb ntawm chromosomes li niam txiv cell, thaum nyob rau hauv meiosis, cov ntxhais hlwb muaj ib nrab ntawm cov chromosomes li niam txiv
Qhov kev ncua deb thiab kev hloov pauv zoo li cas thiab txawv li cas?
Tsis yog, qhov kev ncua deb thiab kev txav chaw tsis zoo ib yam. Qhov deb txhais tau hais tias qhov ntev ntawm txoj kev koj tsiv mus thaum tsiv tawm yog qhov sib txawv ntawm koj qhov chaw pib thiab qhov kawg. Qhov deb txhais tau tias qhov ntev ntawm txoj kev koj tsiv mus thaum qhov kev hloov pauv yog qhov sib txawv ntawm koj qhov chaw pib thiab qhov kawg
