The Functions of Introns: From Junk DNA to Designed DNA
... All genes begin with exons (the protein-coding segments), but most have a variable number of introns within them that alternate with the exons. Introns were discovered in 1977 as a result of observing that the mRNA used to code for proteins was almost always shorter than the DNA from which it had be ...
