5'-TCGAGCTGCCTTCAGTCGT-3'
5'-tcgagctgccttcagtcgt-3'
A single-stranded DNA oligonucleotide consisting of five deoxyguanosine, six deoxycytidine, two deoxyadenosine and six thymidine residues connected by 3'→5' phosphodiester linkages in the sequence T-C-G-A-G-C-T-G-C-C-T-T-C-A-G-T-C-G-T. When part of a longer DNA sequence it can exist in a hairpin structure, with hydrogen bonding linking the six complementary base pairs C<small><sup>2</small></sup>-G<small><sup>18</small></sup>, G<small><sup>3</small></sup>-C<small><sup>17</small></sup>, A<small><sup>4</small></sup>-T<small><sup>15</small></sup>, C<small><sup>6</small></sup>-G<small><sup>15</small></sup>, T<small><sup>6</small></sup>-A<small><sup>14</small></sup> and G<small><sup>8</small></sup>-C<small><sup>13</small></sup>.
