Protein absorption peak
http://www.u.arizona.edu/%7Egwatts/azcc/InterpretingSpec.pdf 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…
