For a viral vector, virulence genes from a virus can be removed and foreign DNA inserted, allowing the virus capsid to be used as a mechanism for shuttling genetic material into a plant or animal cell. The only true path to knowledge is E. coli .". Three things have to be done to isolate a gene from a collection of recombinant DNA sequences: (i) the individual recombinant molecules have to be physically separated from each other, (ii) the recombinant sequences have to be amplified to provide enough material for further analysis, and (iii) the specific fragment of interest has to be .
