Researchers at Stanford University have successfully reapplied natural
enzymes adapted from bacteria to flip specific sequences of DNA back and forth
at will. This switch on/switch off ability means DNA can effectively be
'programmed' - something that could have breakthrough implications for the
treatment of ageing and diseases such as cancers.
The research team call their device a 'recombinase addressable data' module
(RAD). The RAD can modify specific sections of DNA with microbes that determine
how the one-celled organisms will fluoresce under ultraviolet light.
