Matching Pairs DNA and Gel ElectrophoresisOnline version DNA and Gel Electrophoresis by Laura Roy 1 Purines 2 3 Hydrogen bonds for complementary base pairing 3 RFLPs (Restriction Fragment Length Polymorphisms) 4 Gene 5 PCR (Polymerase chain reaction) 6 Gel Electrophoresis 7 DNA 8 DNA Profiling 9 Why DNA travels down a gel 10 Restriction Enzymes 11 2 Hydrogen bonds for complementary base pairing 12 Pyrimidines G and C A and G (contain 2 rings) DNA segments after a restriction enzyme digest. Analyzing bands on a gel to find matching DNA segments to determine paternity, identify a person, or to determine genotype. A and T Recognize specific sequences and cuts DNA at that sequence The negative phosphate group is attracted to the positive electrode. T and C (contain 1 ring) Genetic information A process that makes millions of copies of DNA so that it can be analyzed. A segment of DNA that codes for a protein. The process that separates DNA by the size of the segments.
