If I put 5'-CMV-cDNA-polyA-3' on 5' ITR-3'PolyA-cDNA-CMV3'-3'TR, can cDNA be expressed in rAAV vector?

I use homologous recombination cloning to assemble CMV-cDNA-PolyA (3.9 bp) to AAV transfer vector. After sequencing, I found the fragment is reversely inserted between 5'ITR and 3'ITR. We have...
