The new exon does not introduce new protein-coding sequences. Instead, it contains multiple stop codons that cause protein synthesis to terminate, the mRNA to fall off the ribosome, and then the ...

How can only 25,000-30,000 protein-coding genes in humans produce ... because regulatory sequences that sometimes designate an exon's inclusion into the mature mRNA dictate the exclusion of ...

We also examined the frequency of exon skipping and length variation ... expression will need to be expanded beyond a single coding sequence per gene to include all possible alternative exons ...
