Viruses are as simple as they are 'smart' Posted: 25 Nov 2013 06:13 AM PST Viruses are as simple as they are "smart": too elementary to be able to reproduce by themselves, they exploit the reproductive "machinery" of cells, by inserting pieces of their own DNA so that it is transcribed by the host cell. To do this, they first have to inject their own genetic material into the cells they infect. An international team of researchers has studied how this occurs and how long it takes for this process to be completed.
