Putative secondary structures of the tail regions of HAmo SINE and HAmo LINE. The tail of HAmo SINE shared by HAmo LINE2 and other L2 in sequence starts from 108 bp. The domain has a hairpin region with a GGAUA loop is boxed by a dashed line, which is thought to be a recognition region for the LINE RT in UnaL2 [25, 46]. Thin lines show base pairs. In the LINE-related region of HAmo SINE (start from 108 bp), One nucleotide (143 bp) are different from that of HAmo LINE, that are boxed.
