Gene therapy. Artwork of a recombinant virus spli- cing its genes (orange) into a strand of DNA (deoxyribonucleic acid, blue) within a cell as part of gene therapy. The capsid shell (red) that contains the viral genetic material is inside the cell. The virus' outer coating (envelope) has been left on the surface of the cell. More viruses appear at top right. Viruses replicate by invading cells and substituting some of the cell's genetic material with their own in order to reprogram it to make more viruses. The virus' genetic material can be manipulated by scientists so that it instead places healthy genes in cells to correct inherited genetic disorders.
