Electron Transfer through DNA: Site‐Specific Modification of Duplex DNA with Ruthenium Donors and Acceptors
Abstract
The rate of the electron transfer between two ruthenium centers at the ends of an octanucleotide duplex (metal‐to‐metal distance = 21 Å) was determined to be 1.6(4) × 10 6 s−1. By using automated DNA synthesis techniques, modified oligonucleotides were prepared with a protected phosphoroamidite of 2′‐amino‐2′‐deoxyuridine. The NH 2‐modified oligonucleotides were hybridized with complementary DNA sequences to protect nucleotide bases, and then treated with ruthenium complexes. In this way the ruthenium complex was bound only to the free NH 2 group.

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.
