We touched on introns and exons in my bio class, butunfortunately we didn't really talk about why Eukaryotes haveintrons. It would seem they would have to have some purpose sinceprokaryotes do not have them and they evolved firstchronologically, but I could easily be wrong. Did the junk sectionsof DNA just evolve there by some sort of randomness or necessity asopposed to an actual evolutionary advantage? Why hasn't evolutionstopped us from having introns since they seem to be a 'waste' oftime and DNA? Why do prokaryotes not have introns?
