Figure 4From: Computational prediction and molecular confirmation of Helitron transposons in the maize genomeThe heuristic algorithm for searching 3' end of Helitrons. The 'hairpin loop' and the CTAG termini at the 3' end of known Helitrons are the key characteristics for the identification of new Helitrons. For HelA type Helitrons, the double 'A' is often in the middle of the 'CG' bases in the hairpin loop.Back to article page
