bio-chem q - divu - ArchivalUser - 03-26-2009 An RNA molecule is isolated from d culture of g+ve bac consists 90 nucleotides n contain both dihydrouracil n acetylcytosine residues ,wich of d followin is at 3' end of dis molecule........ 1-TATA 2-CCA 3-POLY-A 4AUG 5-UAG WID EXPLANATION PLZ................. 0 - ArchivalUser - 03-26-2009 is it 2.....CCA as far as i know, tRNA CONTAINS...DIHYDROURACIL... but i am not sure............. 0 - ArchivalUser - 03-26-2009 2-CCA an RNA 90Nucleotides--tRNA 3' end of tRNA is CCA 0 - ArchivalUser - 03-26-2009 CCA 0 - ArchivalUser - 03-26-2009 u all r right but i still don really understand how to figure out dat its d tRNA we r talking about can u expand ur explanation...... it is from uw 0 - ArchivalUser - 03-26-2009 hope to share this-almost same as uw explaination http://en.wikipedia.org/wiki/Transfer_RNA click in other links to see more about mRNA, rRNA,... 0 - ArchivalUser - 03-26-2009 bcz dihydro uraciland acetylcytosine residues are seen only in t-RNA. It's there in Kaplan 0 - ArchivalUser - 03-26-2009 Hi can u plz tell me where in kaplan it is written this way for tRNA? I searched thru it n didnt find it. Thanx |
