tejaswini Posted February 17, 2006 Share Posted February 17, 2006 "it is believed that viruses originated from bacteria. the plasmid from the Hfr strain must have got detached and existed independently, produced a protein coat around itself ,and then out of the cell. Because the plasmid does not have all the genes for life supporting activities the virus always needs a live host." Link to comment Share on other sites More sharing options...
