  DNA-based storage is an emerging storage technology that provides high
information density and long duration. Due to the physical constraints in the
reading and writing processes, error correction in DNA storage poses several
interesting coding theoretic challenges, some of which are new. In this paper,
we give a brief introduction to some of the coding challenges for DNA-based
storage, including deletion/insertion correcting codes, codes over sliced
channels, and duplication correcting codes.
