Cytosine yog ib ntawm plaub lub tsev thaiv ntawm DNA thiab RNAYog li nws yog ib qho ntawm plaub nucleotides uas muaj nyob hauv DNA, RNA, thiab txhua cytosine ua ib feem ntawm cov code. Cytosine muaj cov khoom tshwj xeeb uas nws khi hauv ob lub helix tawm tsam ib qho guanine, ib qho ntawm lwm cov nucleotides.
RNA puas muaj cytosine?
RNA muaj plaub lub hauv paus nitrogenous: adenine, cytosine, uracil, thiab guanine. Uracil yog ib qho pyrimidine uas zoo ib yam li thymine, lwm pyrimidine uas muaj nyob hauv DNA.
Pob DNA thiab RNA muaj lub hauv paus cytosine?
Nitrogenous Base
Txhua nucleotide hauv DNA muaj ib qho ntawm plaub lub peev xwm nitrogenous: adenine (A), guanine (G) cytosine (C), thiab thymine (T). Adenine thiab guanine yog cais raws li purines. … DNA muaj A, T, G, thiab C whereas RNA muaj A, U, G, thiab C.
Puas cytosine tuaj yeem pom hauv DNA?
Cytosine (/ˈsaɪtəˌsiːn, -ˌziːn, -ˌsɪn/) (cim C lossis Cyt) yog ib qho ntawm plaub nucleobases pom hauv DNA thiab RNA, nrog rau adenine, guanine, thiab thymine (uracil hauv RNA).
Puas RNA muaj thymine thiab cytosine?
Plaub lub hauv paus uas tsim cov cai no yog adenine (A), thymine (T), guanine (G) thiab cytosine (C). Bases khub ua ke hauv ob lub helix qauv, cov khub no yog A thiab T, thiab C thiab G. RNA tsis muaj thymine bases , hloov lawv nrog uracil bases (U), uas. khub rau adenine1
