  "definition": "DNA data storage represents digital information in nucleotide sequences that are synthesized, preserved and read back for decoding.",
  "note": "A file identifier can select a group of strands, while separate strand addresses locate fragments within that file. Selection, sequence reconstruction and error correction serve different roles. [organick2018]\n\nPayload bits per synthesized nucleotide and payload bytes per gram describe different accounting boundaries; addresses, coding redundancy and physical copies must be stated. The historical research examples do not specify a general-purpose storage device. [hesela-coverage]",
