abstract：:We have studied the deletion of inverted repeats cloned into the EcoRI site within the CAT gene of plasmid pBR325. A cloned inverted repeat constitutes a palindrome that includes both EcoRI sites flanking the insert. In addition, the two EcoRI sites represent direct repeats flanking a region of palindromic symmetry. A...
