The researchers found COL11A1 and the other targets by comprehensively analyzing the subparts of genes called exons.

The active splicing factor splices out the inhibitory exon in the transcription factor, which turns on the genes that produce collagen.

Further, the genomes of vertebrate animals evolved to feature alternative splicing, in which a single gene can code for more than one protein by leaving out or adding exon sequences.

Those characteristics include the same number of exons, which encode the protein, and phases of introns, which act as interrupters to stop or start splicing of the RNA molecules transcribed from the gene.

Before being turned into proteins, genes are transcribed into introns, or strands of RNA that do not code for proteins, and exons that code for proteins.
