Franklin and Wilkins analyzed DNA by bombarding DNA crystals with X-rays. Their analysis yielded two numbers that sparked interest, 3.4 nm and 0.34 nm. What is the significance of these numbers?
A) It turned out to be just a coincidence.
B) DNA molecules are 3.4 nm long and 0.34 nm wide.
C) The width of a DNA molecule is 3.4 nm, whereas the width of a nucleotide monomer is 0.34m.
D) These numbers tell us there are 10 rungs, or steps, on the DNA "ladder" for every turn of the helix.
E) The 10-to-1 ratio signifies that DNA molecules are ten times longer than they are wide.
