The genomic DNA of housefly larvae was extracted after ultrasound induction, and the structure was analyzed by UV, fluorescence, IR and 1H NMR. The 3'-end of attacin gene was sequenced and compared by means of PCR. All the results indicated that ultrasound induction can destroy the second structure and the base stacking of genomic DNA of housefly larvae, which will result in mismatch repair during DNA duplication and finally change the sequence of DNA, but it has no significant effect on chemical groups and chemical band of genomic DNA.

Article Synopsis
- - The study focuses on cloning the cDNA of Attacin, an antimicrobial peptide from the housefly (Musca domestica), which is crucial for the insect's immune defense against pathogens.
- - The cDNA consists of 778 nucleotides and encodes a 208 amino acid peptide that shares 50%-70% similarity with Attacin peptides from other dipterous insects, indicating a common evolutionary ancestor.
- - The expression levels of the Attacin transcript vary depending on the type of pathogen and the timing of induction, highlighting its role in the housefly’s immune response.
