Multiple Choice
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) These numbers tell us there are 10 rungs, or steps, on the DNA "ladder" for every turn of the helix.
B) DNA molecules are 3.4 nm long and 0.34 nm wide.
C) The 10- to- 1 ratio signifies that DNA molecules are ten times longer than they are wide.
D) It turned out to be just a coincidence.
E) The width of a DNA molecule is 3.4 nm, whereas the width of a nucleotide monomer is 0.34m.
