                         Claim 1 is illustrative of the subject matter on appeal and is reproduced                        
                 below:                                                                                                   
                         1. An isolated and purified DNA molecule comprising a radiation                                  
                            responsive enhancer-promoter operatively linked to an encoding                                
                            region that encodes at least one polypeptide, other than CAT, that one                        
                            desires to have expressed in a radiation responsive manner, which                             
                            encoding region is operatively linked to a transcription-terminating                          
                            region, wherein said radiation responsive enhancer-promoter                                   
                            comprises a portion of the CArG domain from –550 to –50 of an Egr-1                           
                            promoter or a c-jun promoter.
