Interrupted gene: Mutations in exons can affect polypeptide sequence; mutations in introns can affect RNA processing and hence may influence the sequence and/or production of a polypeptide.

#Unit 2. Cellular Organization

Single-base substitutions at the junctions between introns and exons causes an exon to be left out of the product or an intron to be included, or make splicing occur at a different site.

In multicellular eukaryotes most genes are interrupted, and the introns are usually much longer than exons, so genes are considerably larger than their coding regions.
