%0 Journal Article %T Inverted Repeats in Viral Genomes %A M. Spano %A F. Lillo %A S. Micciche %A R. N. Mantegna %J Quantitative Biology %D 2004 %I arXiv %X We investigate 738 complete genomes of viruses to detect the presence of short inverted repeats. The number of inverted repeats found is compared with the prediction obtained for a Bernoullian and for a Markovian control model. We find as a statistical regularity that the number of observed inverted repeats is often greater than the one expected in terms of a Bernoullian or Markovian model in several of the viruses and in almost all those with a genome longer than 30,000 bp. %U http://arxiv.org/abs/q-bio/0410006v1
