intron

A length of bases in a nucleic acid sequence inside of a gene which are not used in encoding the amino acid sequence in the protein. Either a result of that fact that eukaryotic cells haven't evolved the speedy reproduction methods of prokaryotic cells, or a security protocal which god designed to prevent humans from determining the genetic code and the human genome, kind of like a genetic region code

there's three introns and four exons on that gene
