Figure 1: The position of forward and reverse primers, extra segment and homologous regions on the sequenced segment. Forward and reverse primers are shown by arrows. The sequence of homology regions 1, 2 (HR1, 2) and their borders are shown in boxes. Homologous regions are highlighted. Forward and reverse primers are shown by arrows. As shown in this figure, homologous region 2 is a part of the reverse primer sequence. Dashed arrows indicate the direction of sequences.
