Transposons: From 'selfish' genes to key elements in biological processes

 This article has been reviewed according to Science X's editorial process and policies Editors have highlighted the following attributes while ensuring the content's credibility: fact-checked peer-reviewed publication trusted source proofread by International School of Advanced Studies (SISSA) In 2001 the sequencing of the human genome revealed a surprising fact: over 45% of our genome comes from sequences called transposons, "jumping" genes that can move within the genome, generating new copies of themselves through molecular mechanisms of cut-and-paste or copy-and-paste. Because of this characteristic, they are also called "selfish genes," interested only in replicating, in a way similar to the action of viruses.
