Isicelo
1.Le mveliso isetyenziselwa ukwenza i-uridine.
I-2.Isetyenziswe kuphando lwe-biochemical.
I-Uracil isisiseko esiyingqayizivele kwi-RNA kwaye ilingana ne-thymine (T) kwi-DNA.Ngexesha lokubhalwa kwe-DNA, i-DNA idityanisiwe kwi-nucleus nge-enzymes ye-deconvolutive kwaye emva koko idityaniswe kunye neeperi zesiseko zamahhala ukwenza i-strand enye ye-RNA, eba yi-RNA yesithunywa (mRNA).Esinye seziseko ze-pyrimidine, kunye ne-cytosine, yinxalenye ye-RNA.Kwakhona kuqulethwe kwii-precursors ezibalulekileyo zokuveliswa kwee-polysaccharides ezifana ne-uridine diphosphate glucose.Umahluko omkhulu phakathi kwe-RNA kunye ne-DNA kukubunjwa kweswekile, kunye ne-RNA equkethe i-uracil kunye ne-DNA equkethe i-thymine.
