Figure 5: Evolutionary investigation of MER54 and AluSx element during primate evolution. (a) Genomic structure of rhesus monkey TSEN54 gene and primer location. (b) PCR amplification of MER54 and AluSx with various primate DNA samples. M indicates the size marker. (c) Schematic representation of the integration events of MER54 and AluSx in TSEN54 during primate evolution. Mya: millions of years ago.
