Identification of highly conserved elements. (A) The strategy for the identification of conserved elements is described by the scheme above the table. The table shows the numbers of conserved elements identified on different levels of sequence conservation. The inclusion of the human–sheep, and mouse–sheep alignments results in a reduction in numbers of identified elements. This reduction is described by the proportions of identified elements related to the values given for the human–mouse alignment only. (B) Positions of the 20 highly conserved elements (>100 bp, >70% identity) in the mouse sequence (GenBank accession no. AJ320506) that were identified in all three alignments. Additionally, the lengths, G+C content, and special features of the individual elements are shown.
