Figure 3.

Nucleotide sequences at endpoints of p1-ww495 and p1-ww2 deletion alleles. The top three lines show the structures of the indicated alleles and the locations of the sequences given below. Sequences a–d are from the progenitor allele p1-vv9D9A. Sequences e and f are from the derivative alleles p1-ww495 and p1-ww2, respectively. Sequences in italics and underlined represent Ac or fAc sequences. Note that the deletion endpoint in p1-ww495 is joined to the Ac 5′-end, while the deletion endpoint of p1-ww2 is joined to the 3′ fAc end. Small black boxes indicate the locations of sequences that hybridize with p1 genomic fragment 15. Other symbols have the same meaning as in Figure 1.
