DNA fingerprinting involves using restriction enzymes to cut DNA at a specific sequence, resulting in many fragments of different lengths. Gel electrophoresis then separates the fragments according to size. DNA fingerprints produced from four different individuals is shown below. The DNA for Individuals 3 and 4 could NOT be Select one: a. mitochondrial DNA from two people who have the same maternal grandmother (both their mothers had the same mother) b. mitochondrial DNA from two people who have the same paternal grandmother (both their fathers had the same mother) c. nuclear DNA from identical twins d. nuclear DNA isolated from a hair left at a crime scene and a buccal swab from a suspect who was present at the crime
