Exon / Intron structure of some vertebrate genes

    In eukaryotes, the intervening introns separate the expressed exon regions. Intron / Exon organization varies widely among genes: a single intron may constitute a minority of the locus, as in insulin, or multiple introns may make up a majority of the sequence, as in ovalbumin. Some genes contain dozens of introns that constitute >99% of the sequence.
