Question

Retroviruses are enveloped viruses that can be engineered to deliver how many bases of single-stranded RNA?

• A. 500 bases
• B. 1000 bases
• C. 3000 bases
• D. 8000 bases

Hint:

Consider the typical size limits for retroviral vectors in gene therapy applications.

Answer 1

The Correct Option is D

Retroviruses are commonly used in gene therapy and can be engineered to deliver approximately 8000 bases of single-stranded RNA. This RNA is reverse-transcribed into DNA, which integrates into the host genome, enabling stable expression of therapeutic genes.
