Fig. 9

Examples of alignment columns. The figure shows the examples of alignment columns that include the concestor interval Homo–Vertebrata in the transcribed enhancer regions and show brain-specific RNA transcription. The y-axis represents nine example alignment columns and x-axis represents nucleotides of each column, in which gaps, ambiguous nucleotides, and unaligned regions are shown as blank. The species are aligned such that it conforms phylogenetic trees and sorted such that species more evolutionarily distant from humans are placed on the right
