Genetic information A and T Analyzing bands on a gel to find matching DNA segments to determine paternity, identify a person, or to determine genotype. A and G (contain 2 rings) Recognize specific sequences and cuts DNA at that sequence G and C A segment of DNA that codes for a protein. A process that makes millions of copies of DNA so that it can be analyzed. The negative phosphate group is attracted to the positive electrode. T and C (contain 1 ring) The process that separates DNA by the size of the segments.
