Hybridization

In order for a gene to be visible, it must be probed with a length of nucleic acid with the same sequence. These probes are labeled with radioactivity. This program follows the procedures as well as the necessary safety precautions until at the end an autoradiograph is obtained. The dark bands indicate where the labeled DNA probe has bound to the DNA of the same sequence on the filer. This provides the final result. It is from this apparently simple pattern of bands that the information we need is to be found—the source of the exciting developments in biotechnology. (15 minutes)
