Answer 1

It eliminates a lot of unnecessary steps and it incorporates the foreign gene into the host chromosome.

Explanation:

The benefit of utilising a retrovirus as a vector in gene therapy is its ability to quickly enter host cells and introduce the desired gene directly into the host chromosome. This provides the consistent, long-term expression of the inserted gene and reduces the need for further difficult steps in the process.
