Systematic analyses of sequence features have resulted in a better characterisation of the organisation of the genome. A previous study in prokaryotes on the distribution of sequence repeats, which are notoriously variable and can disrupt the reading frame in genes, showed that these motifs are skewed towards gene termini, specifically the 5' end of genes. For eukaryotes no such intragenic analysis has been performed, though this could indicate the pervasiveness of this distribution bias, thereby helping to expose the selective pressures causing it.
