For applications in gene therapy,what is the most favorable characteristic of retroviruses?

Question

Quizplus · Accepted Answer

The integration of the DNA copy of the retroviral genome into the genome of the infected cell allows for long-term expression of the therapeutic gene, which is essential for successful gene therapy. Retroviruses possess the ability to integrate their genome into the host cell DNA due to the activity of the viral enzyme, integrase. This allows the therapeutic gene to be stably expressed in the target cells, leading to the desired therapeutic effect.
