in general (not specific to this crime scene), how is it that Suspect Bob and Suspect Jim will have a different DNA fingerprint (banding pattern) when we run the gels? How do restriction enzymes + Bob's DNA generate different banding patterns than restriction enzyme + Jim's DNA

Answer:

The DNA is cut by a type of enzyme called a restriction enzyme. ... In addition, no two restriction enzymes will cut the same DNA molecule in the same way. Therefore, no two enzymes used to cut the same DNA molecule will give you the same number of pieces nor the same sized pieces of DNA.

The lines (or bands) represent pieces of DNA of different sizes. If two samples come from the same individual, all bands in one sample must match up with all the bands in the other. ... A DNA fingerprint is obtained from the mother, the child, and the alleged father. These fingerprints are compared with each other.
