Figure 2From: ANRIL/CDKN2B-AS shows two-stage clade-specific evolution and becomes conserved after transposon insertions in simiansSplicing signals in ANRIL. (A) Schematic of splicing sites and signals. (B) ANRIL contains significantly more splicing signals in simians than in other mammals and prosimians. Black, red, and ‘?’ indicate conserved, non-conserved, and undetermined splicing signals, respectively. Blanks indicate the absence of exons.Back to article page
