Patent ID: 6849725

Claim:
A deoxyribonucleic acid molecule, consisting of a partially single-stranded, dumbbell-shaped, covalently closed chain of deoxyribonucleoside residues, and containing one or more sequences of the base sequence N 1 N 2 CGN 3 N 4 , wherein N 1 N 2 is an element of the GT, GG, GA, AT or AA group, N 3 N 4 is an element of the CT or TT group, as well as C deoxycytosine, G deoxyguanosine, A deoxyadenosine and T deoxythymidine, wherein its sequence contains a deoxyribonucleic acid sequence of the base sequence AACG TTCTTCGGGG CGTT (SEQ. ID No. 1), and wherein the deoxyribonucleic acid molecule has a length of 40 to 200 nucleotides.
