Model released. Research scientist examining a series of DNA sequencing autoradiograms or "genetic fingerprints". A sample of DNA is cut into fragments by an enzyme and marked with a radioactive tag in preparation for sequencing. The DNA fragments are then separated by electro- phoresis in an agarose gel,moving different distances along the gel according to their size. The resulting banding pattern is preserved by applying a radiographic film to the gel,producing the autoradiograms seen here. In this case,DNA sequencing is being used to study the heritability of late onset diabetes | |
