The negative phosphate group is attracted to the positive electrode. G and C Recognize specific sequences and cuts DNA at that sequence A process that makes millions of copies of DNA so that it can be analyzed. Analyzing bands on a gel to find matching DNA segments to determine paternity, identify a person, or to determine genotype. A and T A segment of DNA that codes for a protein. DNA segments after a restriction enzyme digest.
