Gene Boy is a simple, multifunction DNA sequence analysis tool. 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. With the "clone screen" feature, duplicate a result in a new screen for comparison with a second result. You can even change the "skin" color. Gene Boy was developed for our DNA Interactive site; go to the Genome section to use it in context.
