Electrochemical identification of artificial oligonucleotides related to bovine species. Potential for identification of species based on mismatches in the mitochondrial cytochrome C1 oxidase gene
Bibliographic record
Abstract
Our studies show that electrochemical impedance spectroscopy (EIS) and scanning electrochemical microscopy (SECM) of films of ds-DNA on gold allow us to distinguish between mitochondrial DNA fragments of the cytochrome c(1) oxidase (mt-Cox1) of three related species of the subfamily 'Bovinae' (Bos taurus, Bison bison, and Bison bonasus). In EIS, a perfectly matched DNA gives rise to a considerably larger charge transfer resistance R(ct) compared to mismatched pairings. Differences in charge transfer resistance, ΔR(ct), before and after the addition of Zn(2+) ions provide an additional tool for identification. In addition, all ds-DNA films were studied by SECM and their kinetic parameters were determined. Perfectly matched ds-DNAs are readily distinguished from mismatched duplexes by their lower rate constants. Our system can be used multiple times by dehybridization and rehybridization of capture strands up to the 250 pmole level.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
