"WebIntrons and exons are regions of DNA that make up a gene. Exons are the portions of the DNA that code for a protein, while introns are the non-coding regions of DNA that interrupt the coding sequence of a gene. During the process of transcription, the entire gene (including both exons and introns) is copied into a messenger RNA (mRNA) molecule. " - Role of introns
