Task: Please create a description for a molecule based on its representation.
SMILES: Cc1cn2c(=O)nc1[C@@H]1N(C(=O)NC(=O)[C@]1(C)O)[C@H]1C[C@H](OP(=O)(O)OC[C@H]3O[C@@H]2C[C@@H]3OP(=O)(O)OC[C@H]2O[C@@H](n3cc(C)c(=O)[nH]c3=O)C[C@@H]2O)[C@@H](COP(=O)(O)O[C@H]2C[C@H](n3cc(C)c(=O)[nH]c3=O)O[C@@H]2COP(=O)(O)O)O1
Constraint: Answer the question with complete sentences.
Result: The molecule is a single-stranded DNA oligonucleotide containing four consecutive thymidyl residues, T1, T2, T3 and T4, arranged in the direction from the 5'-terminus to the 3'-terminus, with a (6-4) lesion at the central T2 and T3 residues. It has a role as an epitope.
