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