Figure 7-88Four patterns of alternative RNA splicing

In each case a single type of RNA transcript is spliced in two alternative ways to produce two distinct mRNAs (1 and 2). The dark blue boxes mark exon sequences that are retained in both mRNAs. The light blue boxes mark possible exon sequences that are included in only one of the mRNAs. The boxes are joined by red lines to indicate where intron sequences (yellow) are removed.
