if all the DNA of the Zea mays (corn) haploid genome were stretched out "end-to-end" as B-form DNA, the resulting "molecule" would be 1.8 meters long. How many picograms of DNA does this represent?
Note: adjacent base pairs in B-form DNA are separated by 0.34 nanometers
The molecular weight of an average base pair of DNA is 660 g/mole
1 picogram (pg) = 10^12 grams (g)
1 nanometer (nm) = 10^9 meters (m)
Avogadro's number = 6 x 10^23
