Language-like features in DNA: transposable element footprints in the genome
Department of Chemistry, University of Southampton - Southampton SO17 1BJ, UK
Accepted: 19 September 1996
The observation of language-like features in non-coding DNA has led to suggestions that “junk” DNA could have higher-order functions, possibly associated with controlling gene expression. We propose a physically realistic model which provides an insight into the possible origin of these language-like features. The physical basis of the model is the accumulation of target site duplications produced by multiple insertions of transposable elements at specific nucleotide sequences, followed by precise excision of these elements.
