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