Abstract
The genomic region BC-1 (GenBank acc. No. AB075899) on mouse chromosome 16 has been reported as a genomic region undergoing somatic DNA recombination producing circular DNA and genomic deletion in brain during late embryogenesis. The present study shows that the BC-1 circular DNA production had already started on the 13th day of embryonic age, earlier than the previous observation that the circular DNA production started on the 15th through 17th embryonic day. The BC-1 deletion was also observed in the spleen and ocular lens. In situ hybridization analysis indicated that a human-homologous region in the BC-1 sequence was expressed in the lens at a perinatal period. These data suggest that the somatic DNA recombination in the BC-1 region is not restricted to brain tissue, and that the BC-1 DNA recombination relates to lens development.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
