WebAbstract. Recombinant adeno-associated viral (rAAV) vector mobilization is a largely theoretical process in which intact AAV vectors spread or "mobilize" from transduced cells … WebA: Both wild-type and many rAAV hold a single stranded DNA genome (ssAAV), but rAAV have also been engineered to house a double stranded DNA genome (dsAAV).Transgene expression following infection with ssAAV requires that a second strand of DNA is synthesized within the host cell to convert the ssAAV genome into double stranded DNA.
