Proposed model for rhesus monkey SNORA25duplication. A. 3' flanking sequence alignment of eleven rhesus monkey SNORA25 paralogs. The colored sequences represent different consensus motifs. Red, green, and pink blocks are poly(A) structures. Yellow and blue boxes represent two other consensus sequences. B. Proposed model for rhesus monkey SNORA25 duplication. The adjacent T and A are the two conserved nucleotides at the immediate 5' end of SNORA25. Different colored blocks represent various consensus motifs as described in A above. Poly(A) sequences are highlighted in red. Target site duplications (TSDs) are shown with brown arrows.
