The Crystallization and Structure Analysis of Oligonucleotide Sequences
Bibliographic record
Abstract
Until 1976, the study of nucleic acid structure was exclusively the domain of fiber diffractionists. Between the original Watson-Crick structure in 1953 and this date, there was considerable activity in refining the original B-form model of DNA and extending the approach to other polymorphs and a number of synthetic, repetitious polynucleotides, all of which were based on data from fiber-diffraction samples. These studies reached their zenith with the development and use of a "linked-atom," least-squares refinement procedure for the optimization of mono-or dinucleotide repeat units against the relatively sparse para-crystalline diffraction data from ordered fibers. It is a tribute to the sophistication of these analyses, in spite of the inherent limitations of fiber data, that the refined "canonical" A- and B-DNA double helices are still major reference pomts for many studies ().

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.
