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