(a) Pairwise sequence alignment of the 11q23 repetitive site (chr11:114,604,212-114,625,620) in the human genome against 30 mammalian genomes. Vertical lines with darker grayscale color represent higher alignment quality, whereas a horizontal single or double line represents a lack of sequence homology between the human and the aligned genome. (b) Comparison of the consensus motif logos of the repeat sequence from the human, chimpanzee, or EBV genome showing that while the 18bp palindromes are conserved amongst all three species, the interspersed sequences are distinct between the primates and EBV.
