IGB start screen. Close-up on BRCA1, with PCR primers. Right-click to run BLAST. RNA-Seq coverage graphs highlight alternative splicing. Sliced view trims introns; makes gene structures easier to understand. Use ProtAnnot to search InterProt for conserved motifs, find out how splicing changes gene function. What is IGB? IGB is a fast, flexible, and free genome browser you can use to explore & visu
