Open in App
Solution
The correct option is E Retrovirus
In gene therapy trials, the retrovirus is used as a vector to treat X-linked severe combined immunodeficiency (X-SCID) represent the most successful application of gene therapy. The retrovirus genetic material is in the form of RNA molecules, and their hosts genetic material is in the form of DNA. When a retrovirus infects a host cell, it will introduce its RNA together with some enzymes, namely reverse transcriptase and integrase, into the cell. This RNA molecule from the retrovirus must produce a DNA copy from its RNA molecule before it can be integrated into the genetic material of the host cell. The process of producing a DNA copy from an RNA molecule is termed reverse transcription.
