Molecular characterization of a mouse Y chromosomal repetitive sequence that detects transcripts in the testis
Bibliographic record
Abstract
145SC5 is a Y chromosomal repetitive sequence isolated from a BALB/c mouse and is unique in that it detects poly(A)-containing transcripts in the testis. We determined nucleotide sequences of 145SC5 and a related cDNA clone designated PC11 and compared their sequences to that of pYMT2/B, another related cDNA clone. 145SC5 and PC11 are almost identical (97%), while PC11 and pYMT2/B share 84% identity. In situ hybridization and Southern blot analysis with XXSxr male mice demonstrated that 145SC5-related sequences were distributed over the entire length of the Y chromosome including the short arm. Two types of Y chromosome are present in inbred mouse strains: the Mus musculus musculus type and M.m. domesticus type. Among 26 inbred strains surveyed, 145SC5 detected polymorphims only in the M.m. domesticus Y chromosome.

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.
