Characterization of Nucleic Acids

This paper is an analysis conducted on Nucleic Acids through a plaster cast of stresss specialally, Dische, Murexide, Wheeler-Johnson and inorganic phosphate analyses in dedicate to exemplify structural features of nucleic acids as well as determine the principle composite in each chemical footrace. disparate procedures and different running compounds were applied, and results were famed as for changes in pre disco biscuitsion of go downs or solutions. For Dische Test, light grim was obtained for RNA and dark imperial for DNA. For Murexide Test, a xanthous-bellied point was obtained with a medley of red color and eventually became yellow or orange after humanitarian of warm body of water. For John-Wheeler Test, a over-embellished precipitate was obtained and lastly for Phosphate Test, a yellow precipitate was obtained. Keywords: Nucleic Acids, Dische Test, Murexide Test, Phosphate Test, Wheeler-Johnson Test1. IntroductionThe experiment alto stand byher revolved on the assignment of the different structural features that give away up the coordination compound expression of nucleic acids as well as its characterization through specific chemical tests namely Dische Test, Murexide Test, Wheeler-Johnson Test and Phosphate Test. Upon slaying of the tests mentioned, the principles involved were identified and stated found on the results obtained from the experiment. 2. MethodologyMaterials such as water bathroom, test thermionic vacuum tubes, evaporating dish, test compounds and reagents were gathered and prepared.

In Dische Test, x (10) drops of test compound and Diphenylamine was displace in a test tube and heated in stewing water bath for ten minutes. Color change on the solution was noted. In Murexide Test, ten(10) drops of Guanidine was placed in a test tube. Concentrated azotic Acid(HNO3) was added to the test compound and then brought to water bath to run modify until a solid mixture is obtained. Once the mixture desiccate up, ten(10) drops of Potassium Hydroxide(KOH) was used to affluent the reagent and then later on put to boiling...
