Cassette exons involve alternative splicing where a particular exon may be included or excluded in the final mRNA molecule, resulting in two different protein products. This is the most common type of alternative splicing in animals and involves making mRNA molecules that lack a complete exon. Intron retention involves the retention of an intron in the mRNA molecule, mutually exclusive exons involve alternative splicing where one exon is chosen over another, alternative promoters involve the use of different transcription start sites, and alternative splice sites involve choosing different splice junctions within an exon or intron.
