Use our simple bioinformatics tool, Gene Boy, to analyze DNA sequences. In striving to create a simple and engaging interface, we have wrapped sophisticated algorithms in an attractive multimedia "skin." Gene Boy is a program with the sense of being a real, onscreen object. Draw sequence data from buttons on the left side of the console and perform bioinformatic functions with buttons on the right: transform/format DNA sequence, analyze nucleotide composition, search for restriction sites or other short motifs, and find open reading frames. The "clone screen" feature opens a duplicate screen for comparison with a second result. Just for fun, you can change the color of Gene Boy.
