Molecular cloning of insulin‐like growth factor‐I complimentary DNA and promoter region in the domestic duck (<i>Anas platyrhynchos</i>)*
Bibliographic record
Abstract
ABSTRACT Complementary DNA (cDNA) and the flanking region of insulin‐like growth factor‐I (IGF‐I) of domesticated duck were cloned. The nucleotide sequence analysis of the cDNA showed seven and eight bases different, respectively, from chicken and turkey IGF‐I cDNA within the coding region. The amino acid sequence of prepro IGF‐I differed by one and two amino acids from those observed in chicken and turkey, respectively. However, no amino acid substitution was observed in the mature IGF‐I region. Sequence analysis of the promoter region and exon 1 of the duck IGF‐I revealed a high degree of similarity to that of the chicken IGF‐I gene. These results suggest that the mechanisms which regulate expression of the IGF‐I gene may be widely conserved in avian species.

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.
