Daim ntawv thov
1.Cov khoom no yog siv los ua ke uridine.
2.Siv hauv kev tshawb fawb biochemical.
Uracil yog lub hauv paus tshwj xeeb rau RNA thiab sib npaug rau thymine (T) hauv DNA.Thaum lub sij hawm transcription ntawm DNA, DNA yog deconvoluted nyob rau hauv lub nucleus los ntawm deconvolutive enzymes thiab tom qab ntawd ua ke nrog dawb puag khub los ua ib tug tib strand ntawm RNA, uas dhau los ua messenger RNA (mRNA).Ib qho ntawm cov pyrimidine hauv paus, ua ke nrog cytosine, yog ib feem ntawm RNA.Kuj tseem muaj nyob rau hauv qhov tseem ceeb precursors rau zus tau tej cov polysaccharides xws li uridine diphosphate qabzib.Qhov sib txawv tseem ceeb ntawm RNA thiab DNA yog cov piam thaj muaj pes tsawg leeg, nrog RNA muaj uracil thiab DNA muaj thymine.
