我们研究了典型的非编码DNA序列之一Alu重复序列中可能存在的准周期性质。用准周期矩阵算法计算了不同系列Alu重复序列左右单体的准周期。有趣的是，所有家族的右侧单体在其序列中显示出明显的准周期8，而左侧单体显示出准周期8或5。我们的结果表明，在大多数Alu重复序列中存在着共同的准周期。这可能有助于进一步探讨Alu重复序列的可能功能。
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.
