Repetitive DNA: Evolution

Abstract

Repetitive DNA sequences form a substantial fraction of the genomes of most eukaryotes. Far from conferring fitness benefits to their host, in most cases repetitive sequences are maintained solely by their ability to replicate within the genome.

Keywords: tandem‐repetitive DNA; transposable elements; ‘selfish DNA’ hypothesis; mechanisms of copy‐number change; natural selection; copy‐number variation
