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