In the book The Vital Question the author argues that nuclei were invented to protect against the original mithocondrial DNA: > Introns are the result of "a barrage of genetic parasites" that early eukaryotes faced from their own endosymbionts; nuclei evolved as a defence against this, allowing spliceosomes to remove introns from transcribed messenger RNA before ribosomes can translate them into proteins. |
