Hairpin‐DNA memory Using Molecular Addressing

Takinoue, Masahiro, Suyama, Akira·2006·Small

Abstract

A memorable loopy address: A simple molecular memory, named the “hairpin-DNA memory”, has been developed (see schematic). The memory employs the temperature-controlled conformational transition of hairpin-DNA strands in memory writing and erasing and allows parallel addressing of a very large memory space without physical wiring. Experiments on repetitive memory writing and erasing demonstrated that the molecular addressing was highly selective and parallel.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • DNA strands were used as molecular memory by thermally transitioning between a hairpin structure (unwritten state) and a duplex structure (written state).

    “In an early example, DNA strands were used as “molecular memory” by transitioning thermally between a hairpin structure (unwritten state) and a duplex structure (written state).118”
  • In that molecular memory system, fluorophore/quencher pairs cause the fluorescence output to reversibly switch between two defined states, producing a binary signal.

    “The oligonucleotides were appended with fluorophore/quencher pairs; as the thermal cycling occurs, the fluorescence output reversibly switches between two defined states to produce a binary signal.”

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.
