The standard orcinol test for estimating RNA is modified and developed as a specific method for the determination of RNA in the presence of DNA and proteins. ESTIMATION OF RNA BY (RIBOSE SUGAR) BY ORCINOL METHOD ยท Estimation of DNA (Deoxy Ribose) by Diphenyl Amine Method. Biochemistry and. Estimation of RNA (Orcinol method). Principle: This is a general reaction for pentoses. Acid hydrolysis of RNA releases the ribose sugar and this in the presence.
