DNA that is 100ng/µl, and you want to use 1µg of DNA. How much of the DNA
solution should you use?
Thank you
1 AnswerBiology5 years ago20µg/µl is equal to:?
- 0.02mg/ml
- 0.2ng/µl
- 0.02µg/ml
- 20,000ng/µl
- 20mg/ml?
Thank you

1 AnswerChemistry6 years agoLimit of detection question?
You want to determine the amount of cholesterol in the blood of a newborn infant. You know it will be around 5 mM. The detection limit of the method you are going to use is about 20 nm and you can only take about 20 microliters of blood. Will this be enough?
Thank you

2 AnswersMathematics8 years agoSlope from absorbance help?
Finding the slope of a line from a chart recorder?
I'm trying to find the gradient in order to calculate the initial velocity.
The pen moved at 10 mm/min. I need the slope to calculate the initial velocity of an enzymatic reaction.
Other recorder settings: 0-1 V, full scale deflection of 0-2 absorbance units, not sure if that is relevant.
