Fig. 1From: Phylogenomic analysis reveals splicing as a mechanism of parallel evolution of non-canonical SVAs in hominine primatesSchematic representation of an SVA element. The element consists of (from 5′) TCTCCC hexameric repeats, an Alu-like domain, a VNTR (Variable Number of Tandem Repeats) region and an endogenous retrovirus-derived SINE-R at the 3′. The polyadenylation signal is directly followed by the polyA tail (pA)Back to article page
