If all the DNA of 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?
use the following as knowns:
Adjacent base pairs in B-form DNA are separated by 0.34 nm
mol. weight of base pair of DNA is 660 g/mole
1 pg = 10^-12 g
1 nm = 10^-9 m
avogadro's number = 6*10^23
