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