DNA concentration is estimated by measuring the absorbance at 260nm, adjusting the A260 measurement for turbidity, multiplying by the dilution factor and using the relationship that an A260 of 1.0=50 microgram/ml pe dsDNA.
The answer is 12nm.

Can you pleasee answer these questions regarding the experiment of DNA quantification. What is “blank” and why do we use it in DNA quantification? If you are told to analyze DNA samples that we extracted from buccal swabs, what would you use as a blank? 3. Explain in details: a. Concentration b. A260/A280 ratio c. A260/A230 Why are those measurements used, how do you know which concentration to expect if you used the commercial kit for DNA extraction, what is...

My question is, how do I solve this question. I don't just want the answer, I want to know step by step how to do it. A 2.5 mg/ml stock solution was diluted as described in the table below and then the absorbance of each dilution was determined and presented in the table below. Using this information, what is the concentration in mg/ml (to two decimal places) of an unknown sample with an absorbance of 0.16? (Hint: You will have...
