Critical 5′ and 3′ control elements from Cnidaria can be identified by cloning PCR amplified portions of 5′ and 3′ {HEAD ~ flanking sequences} of {TAIL ~ known metazoan genes} into reporter expression vectors, and measuring their effect on reporter expression following transformation of the metazoan hosts
