E coli bacteria (IMAGE)
Caption
Top row: E coli bacteria containing a retron break apart the membranes in the cell around 15 minutes after infection (center) Red reveals holes in membranes as cells die. (Right) 45 minutes post infection with a phage, many cells have died, but a few remain to restart growth. Bottom: bacteria lacking this retron look fine after 15 minutes, but 45 minutes later, the infected cells have died and the viral DNA has spilled out, on its way into the remaining few cells
