Example text

In the example, the recognition sequenceofthe commonly used restriction enzyme EcoRI is presented (5'-GAATTC). The two individuals differ in DNA sequence at one potential recognition sequence. The restriction enzyme cuts in one but not the other (indicated by X), generating restriction fragments of different length. The fragments are separated by gel electrophoresis, and visualizedby binding of a specific radioactive DNA probe. In practice, restriction fragment length polymorphisms are found empirically, by randomly testing different DNA probes with different restriction enzymes, until a combination is found which distinguishes between the genotypes of interest.
