The invention provides a number of strategies for transferring and/or evolving gene(s) associated with cellular DNA uptake so that they confer or enhance DNA-uptake capacity of a recipient cell. Evolution is achieved by recursive cycles of recombination and screening/selection. One such strategy entails...http://www.google.com.au/patents/US6482647?utm_source=gb-gplus-sharePatent US6482647 - Evolving susceptibility of cellular receptors to viral infection by recursive recombination
