For . double stranded DNA, the commonly accepted average … One of the most commonly used practices to quantitate DNA or RNA is the use of spectrophotometric analysis using a spectrophotometer. A spectrophotometer is able to determine the average concentrations of the nucleic acids DNA or RNA present in a mixture, as well as their purity. Spectrophotometric analysis is based on the principles that nucleic acids absorb ultraviolet light i… tekst pesme jana abu dhabi
