Noncoding DNA comprises a substantial fraction of the genomes of higher eukaryotes. It consists largely of introns, simple repetitive DNA sequences, and sequences derived from mobile genetic elements (i.e. transposable elements).


  • intron;
  • transposon;
  • repetitive DNA;
  • pseudogenes;
  • saltatory replication;
  • retrotransposon
