You have a very small weighing DNA portion of a cell. You want to know how many cells you need to isolate .001 mg of the DNA. If you divide out the amount you need .001 by .000000000002 (which is the weight of one amount of DNA) then you get how many cells needed : )
Your answer should be 500,000,000 cells
The DNA in a human cell weighs approximately 2.0 x 10-12 grams. Calculate how many cells you would need to use to isolate 1 mg (milligram or 1x10-3 grams) of DNA, assuming you can get all the DNA out of a cell.
I honestly don't know how to start and solve this problem...
