Abstract

fetched live from OpenAlex

Sister chromatid exchange (SCE) refers to the interchange of DNA between replication products. The technique for detecting such exchanges takes advantage of the semiconservative nature of DNA synthesis. 5'-bromodeoxyuridine (BrdU) is incorporated into the newly synthesized DNA. Using standard culturing techniques, Colcemid is added to the culture and conventional cytogenetic preparations are made. Differential staining with Hoechst dye and Giemsa allows the newly synthesized DNA within a chromatid to be recognized, since BrdU incorporation results in much weaker staining. SCEs represent a point of DNA template exchange during strand synthesis, visualized as asymmetric chromatid staining or "harlequin" chromosomes.

Full frame distilled prediction

Teacher imitation

Not 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.
