Re-integration of full-length wild type Dronc cDNA (LP09975) into the attP site present in DroncKO. The Dronc sequence contains is appended by GFP and APEX2 tags at the C-terminal end of the Dronc open reading frame, and is surround by FRT sites. This excisable cassette is followed by a QF driver sequence - this sequence is not expressed because of the upstream FRT cassette.
