Abstract

Abstract DNA digital storage provides an alternative for information storage with high density and long-term stability. Here, we report the de novo design and synthesis of an artificial chromosome that encodes two pictures and a video clip. The encoding paradigm utilizing the superposition of sparsified error correction codewords and pseudo-random sequences tolerates base insertions/deletions and is well suited to error-prone nanopore sequencing for data retrieval. The entire 254 kb sequence was 95.27% occupied by encoded data. The Transformation-Associated Recombination method was used in the construction of this chromosome from DNA fragments and necessary autonomous replication sequences. The stability was demonstrated by transmitting the data-carrying chromosome to the 100th generation. This study demonstrates a data storage method using encoded artificial chromosomes via in vivo assembly for write-once and stable replication for multiple retrievals, similar to a compact disc, with potential in economically massive data distribution.

  • The dChr was replicated with high fidelity, no mutation appeared after the 100th generation of replication, and the encoding method was tolerant toward a comparatively low accuracy of Nanopore sequencing, enabling fast retrieval of reliable data.

    “Moreover, the dChr was replicated with high fidelity, no mutation appeared after the 100th generation of replication, while the encoding method used in this setup was tolerant toward a comparatively low accuracy of Nanopore sequencing, enabling the fast retrieval of reliable data [69].”

    From DNA Data Storage. (2023) · cites this paper as [69]

    The Results report that the authors constructed a 254,886-bp yeast artificial chromosome encoding 37,782 bytes—approximately 38 KB—comprising two pictures and a video clip. Our copy does not describe the chromosome as circular, so that part of the claim is not supported. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
