»Dr Jon Heras DescriptionDNA uptake by a cell. In this image, a foreign strand of DNA (blue) is shown spliced into the host's genome, giving the cell new functions through the new DNA being expressed. There are numerous examples of new DNA being incorporated into cells and expressing its genes. For instance, specific genes can be artificially introduced to bacteria to confer desired properties, such as the ability to produce the hormone insulin. Alternatively, retroviruses use this technique to hijack the cell for its own replication factory, eventually killing the cell and propagating the virus.
