title: Quasiperiodic property in Alu repeats.
abstract: We investigate the possible quasiperiodic property in the sequences of Alu repeats, one of typical noncoding DNA sequences. We calculated the quasiperiods of the right and left monomers of Alu repeats of different families with quasiperiodic matrix algorithm. It is interesting that the right monomers of all families show significant quasiperiod 8 in their sequences while the left monomers show quasiperiods 8 or 5. Our results indicate that there exist common quasiperiods in most Alu repeats. This may be helpful to further explore possible functions of Alu repeats.
