Abstract
A 340-bp EcoRI fragment of alpha satellite DNA from human chromosome 12 has been isolated and used in molecular cytogenetic and genetic studies. The clone, pSP12-1, detects tandemly repeated 1.4-kb repeat units at the centromeric region of chromosome 12. By fluorescence in situ hybridization, biotinylated pSP12-1 is highly specific for chromosome 12 and has been used to confirm an i(12p) in a case of Pallister-Killian syndrome, both in metaphase spreads and in interphase nuclei. A dominant DNA polymorphism for the centromeric D12Z3 locus is detected with the enzyme TaqI. In addition, a high frequency of D12Z3 array length polymorphisms can be detected using pulsed-field gel electrophoresis. The D12Z3 array has been measured by pulsed-field gel electrophoresis to span approximately 2,250-4,300 kb at the centromeric region of chromosome 12.

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 it
