Question:
A sample of DNA is prepared for fingerprinting. It contains three fragments of different sizes, all having charge -8e. After a certain amount of time, the fingerprint pattern in Figure P17.76 is found. What are the relative sizes of the three fragments? That is, assuming the fragments are spheres with radii rA, rB, and rC, what are the ratios rB/rA and rC/rA?
