RNA yog qee yam zoo sib xws rau DNA ; lawv ob leeg yog nucleic acids ntawm nitrogen-muaj hauv paus koom nrog qab zib-phosphate qaum qaum. DNA muaj Thymine, qhov twg as RNA muaj Uracil. RNA nucleotides suav nrog qab zib ribose, tsis yog Deoxyribose uas yog ib feem ntawm DNA.
Ib yam li ntawd, nws tau nug, qhov zoo sib xws thiab qhov sib txawv ntawm DNA thiab RNA yog dab tsi?
Zoo sib xws : Ob leeg yog tsib-carbon pentose qab zib uas tsim nucleotides nrog puag thiab phosphate (qab zib + puag + phosphate = nucleotides). Bases: Cov DNA yog tsim los ntawm adenine, guanine, cytosine thiab thymine thaum lub RNA yog tsim los ntawm adenine, guanine, cytosine thiab uracil.
Tsis tas li ntawd, DNA thiab RNA zoo li cas? DNA yog ib tug ntev polymer nrog deoxyriboses thiab phosphate qaum. Muaj plaub lub hauv paus nitrogenous sib txawv: adenine, guanine, cytosine thiab thymine. RNA yog ib tug polymer nrog ib tug ribose thiab phosphate qaum. Plaub lub hauv paus nitrogenous sib txawv: adenine, guanine, cytosine, thiab uracil.
Tsis tas li ntawd, DNA thiab RNA muaj dab tsi zoo sib xws?
Ob leeg DNA thiab RNA muaj plaub lub hauv paus nitrogenous txhua-peb ntawm lawv sib koom (Cytosine, Adenine, thiab Guanine) thiab ib qho sib txawv ntawm ob ( RNA muaj Uracil thaum DNA muaj Thymine). Ib qho tseem ceeb tshaj plaws zoo sib xws ntawm DNA thiab RNA yog lawv ob leeg muaj ib lub pob txha phosphate uas cov hauv paus txuas.
DNA thiab RNA zoo li cas quizlet?
DNA txawv dua li RNA vim nws muaj: deoxyribose rau cov suab thaj, thymine es tsis txhob uracil, thiab nws yog ob zaug tso tseg. DNA thiab RNA yog zoo sib xws Nyob rau hauv cov qauv vim lawv ob leeg muaj: ib tug qab zib-phosphate qaum qaum, thiab nitrogen puag rungs- yeej ob leeg ua los ntawm nucleotides.

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)
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
Vim li cas cov nqi zoo thiab tsis zoo nyiam?
Tus nqi tsis zoo xav muab nws cov electrons los ua qhov nruab nrab yog li nws nyiam qhov zoo ntawm nws. Ntawm qhov tod tes, ib tug zoo chargere yuav tsum tau electrons los ua nruab nrab, yog li ntawd nws txav mus rau tus nqi tsis zoo
Vim li cas tsis zoo thiab tsis zoo yog qhov zoo?
Thaum koj muab qhov tsis zoo los ntawm qhov tsis zoo koj tau txais qhov zoo, vim tias ob lub cim tsis zoo raug muab tso tseg
Koj yuav ua li cas thiaj paub tias kev sib raug zoo yog qhov zoo lossis tsis zoo?
Qhov zoo correlation coefficient txhais tau hais tias raws li tus nqi ntawm ib qho kev sib txawv nce, tus nqi ntawm lwm qhov sib txawv nce; raws li ib tug txo qhov qis dua. Qhov tsis zoo correlation coefficient qhia tau hais tias raws li ib qho kev sib txawv nce, qhov txo qis, thiab vice-versa
