The “vertebrate” section contains the genes historically associated with coding for proteins, comprising exons separated by introns. The HERV section contains all of the HERV inserts, including complete HERVs, defective HERVs and isolated LTRs. The LINEs and SINES (long interspersed and short interspersed repetitive elements) are classed as retro-transposons. The DNA transposons probably originated through DNA viral insertion.
