I don't think you would refer to the raw sectors on your harddrive as a data structure. It may be more useful to view DNA as a just storage medium.
There's an encoding scheme on top of the nucleotides -- amino acids are encoded with trinucleotides. The RNA sequence AUG can be used as a start signal to indicate that peptide synthesis should begin at that point (it can also be used to encode the residue Methionine). Other sequences encode splice sites, these are used to signal the removal of sequences called introns.
Still other sequences (DNA binding sites, like the famous TATA box) have a high affinity for protein (those with DNA binding domains). The presence or absence of enhancers or suppressors can activate or deactive protein synthesis.
DNA also contains error checking information. Eukaryotic DNA undergoes methylation (think of this as adding meta-data to the DNA). After cells undergo replication, the new DNA is untagged. When error-checking enzymes happen upon a mismatch in the DNA, they remove the untagged base. There are also unrecoverable errors. For example, two adjacent Thymine bases can undergo cross-linking upon ultraviolet exposure -- the bases get stuck together. This sort of error can contribute to melanoma.
I don't think that the data structure analogy is appropriate for DNA, but there are certainly data structures encoded on top of it.
