Question

The most common vectors used in DNA therapy experiments are _____.
A) modified human cells
B) retroviruses and adenoviruses
C) antisense oligonucleotides (AONs)
D) bacteria
E) naked DNA

Accepted Answer

Retroviruses and adenoviruses are commonly used as vectors in DNA therapy experiments. They are able to efficiently deliver genetic material into target cells and have been extensively studied and optimized for this purpose. Modified human cells may also be used, but are less commonly utilized. Antisense oligonucleotides and naked DNA have limitations in terms of delivery efficiency and potential immunogenicity, while bacteria pose safety risks.
