Construct: Nucleotide substitution: U?A. Nucleotide substitution: C?A. Nucleotide substitution: G?A. Nucleotide substitution: U?A. Nucleotides 6-96 of the nos 3'UTR, with the above mutations in stem-loops II and III of the TCE sequences, has been inserted into a NheI site within the αTub84B 3'UTR sequences.
Expression of nosαTub84B.3'UTR.nosTCEIIA.IIIA.Scer\UAS in the dorsal pouch epithelium, under the control of Scer\GAL4HD34A, causes lethality in 25% of flies.
