You extract DNA from human tissue similar to how we did extracted the DNA from a kiwi in the lab, and determine that 100 ml of raw, unprocessed tissue yield 20 ml of DNA extract with a DNA concentration of 400 ng/µl. From microscopic observations you estimate that each cell occupies a volume of (20 µm)3. From this data, estimate the number of nucleotides per cell, each with an average molecular weight of 300 g/mol. How does your result compare to the established size of the haploid human genome of roughly 3 billion basepairs? Speculate on reasons for any discrepancies.

This is math, so where are your calculations?
