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