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