英文摘要

For sufficiently long genomic sequence, the frequency of any short nucleotide fragment on one strand is approximately equal to the frequency of its reverse complement on the same strand. Despite being studied over two decades, the precise mechanism involved has not yet been made clear. In this study, we calculated the high order intra-strand partial symmetry (IPS) for 14 animal species by using a fixed sliding window method to scan each genome sequence. The study showed that the IPS was positive associated with organismal complexity measured by the number of distinct cell types. The results indicated that the IPS might be resulted from the increasing of functional non-coding DNAs, and plays an important role in the evolution process of complex body plans.
