Description: The molecule is a single-stranded DNA fragment comprised of one deoxyadenosine, four deoxycytidine, three thymidine and two deoxyguanidine residues connected by 3'->5' phosphodiester linkages in the sequence CTGCCTTCAG. It can exist as a hairpin structure, 5'-d [CTG(CCTT)CAG]-3', consisting of a four-nucleotide loop (CCTT) with a stem of three base-pairs, C-G, T-A and G-C.
