FlyBase curator comment: TI{FRT.Tub.GAL80.O} represents DNA inserted into the genome where the inserted DNA contains sequence encoding Scer\GAL80αTub84B.PL and at least one FRT site and is not flanked by transposable element ends. Other sequences may be present in the inserted DNA and the precise sequence inserted may differ for different insertions of the construct. For details of what is inserted into the genome for an individual insertion of TI{FRT.Tub.GAL80.O}, see the description in the insertion report and in any allele reports associated with that insertion.
