question 39

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.
