SOLVED: The purity of DNA absorbance extractions is measured by calculating the ratio between the peak of DNA (A260) and the absorbance peaks of common contaminants like proteins which have a peak absorbance at 280 nm (A280) or chaotropic salts which absorb strongly at 230 nm (A230). For DNA, an A260/A280 ratio of  1.8 and/or an A260/A230 ratio of 1.8-2.2 is generally accepted as "pure". What are the A260 and A230 OD values for your DNA extraction? Based on these values, how pure is your DNA ext

VIDEO ANSWER: To determine the purity of d n a sample, we need to calculate the ratio of the absorbent b, so the ratio of study, which should be between 60 and…

DNA from a newly discovered virus was purified and UV lightabsorption was followed as the molecule was slowly heated. Theabsorbance increase at the melting temperature was only 10%, whatdoes this result tell you about the structure of the viral DNA andWhy?
