Abstract

Genetic information is encoded in DNA, perpetuating generational transmission of species-specific genetic material. However, DNA sequences are constantly written and rewritten, thus promoting evolution and adaptation to occur at both the cellular and organismal levels. This dynamic process can be facilitated by mobile DNA elements that translocate throughout the genome. While transposable elements are a classic example of mobile DNA, my colleagues and I propose that extrachromosomal circular DNA (ecDNA) represents another class of mobile DNA element. This well documented but poorly studied class of genetic element introduces a new layer of genomic dynamism that reengineers genetic programs and shapes host biology.
