Telomerase caught in the act
Bibliographic record
Abstract
The stable linearity of eukaryotic chromosomes depends on special characteristics of their ends, the telomeres. Accurate telomere function in turn requires a sustained presence of repeated DNA elements, which are maintained by the enzyme telomerase. The telomerase holoenzyme is composed of both protein and RNA, and its functions rely on proper expression, maturation, trafficking and assembly of these components. Conflicting models for the recruitment of telomerase at telomeres have been proposed; one suggests a local activation of telomerase at short telomeres, while the other proposes that telomerase is recruited only at short telomeres. To discriminate between these models and investigate the cell cycle-dependent regulation of telomerase in living cells, a GFP reporter system to visualize the yeast telomerase RNA has been recently developed. This assay shed new light on the mechanism of recruitment of telomerase to telomeres, and it uncovered a hitherto unrecognized mechanism for restricting telomerase access to telomeres.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
