Today’s tip of the week is introducing dbRIP, a database of Retrotransposon Insertion Polymorphisms in Humans. The dbRIP database, as you can tell from the title, is a focused resource on one subject: Retrotransposons in humans. Though focuses, retrotransposons are an important aspect of the human genome comprising 40% of it. They have an effect and a useful branch of study. This databases uses a local installation of the UCSC Genome Browser annotated with the RIP data. The tip movie (click the graphic to start) introduces you to the database. If it is something that interests you, you can learn more about how to use this database from the free UCSC Genome Browser tutorials at OpenHelix, since this database uses the same software.
