Asymmetrically distributed oligonucleotide repeats in the Caenorhabditis elegans genome sequence that map to regions important for meiotic chromosome segregation
Bibliographic record
Abstract
The roundworm Caenorhabditis elegans has a haploid karyotype containing six linear chromosomes. The termini of worm chromosomes have been proposed to play an important role in meiotic prophase, either when homologs are participating in a genome-wide search for their proper partners or in the initiation of synapsis. For each chromosome one end appears to stimulate crossing-over with the correct homolog; the other end lacks this property. We have used a bioinformatics approach to identify six repetitive sequence elements in the sequenced C.elegans genome whose distribution closely parallels these putative meiotic pairing centers (MPC) or homolog recognition regions (HRR). We propose that these six DNA sequence elements, which are largely chromosome specific, may correspond to the genetically defined HRR/MPC elements.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
