Cover Feature: Quick Click: The DNA‐Templated Ligation of 3′‐<i>O</i>‐Propargyl‐ and 5′‐Azide‐Modified Strands Is as Rapid as and More Selective than Ligase (ChemBioChem 19/2018)
Bibliographic record
Abstract
The cover feature picture shows how DNA-templated, copper-mediated azide–alkyne cycloaddition (CUAAC) with 3′-O-propargyl and 5′-azide-terminated oligonucleotides is extremely rapid, reaching completion within minutes. Not only is the reaction fast, but also highly selective when compared with T4 DNA ligase. At temperatures between the dissociation temperatures of the matched and the single base pair–mismatched systems, excellent selectivities are observed for CUAAC that are superior to that from the enzyme. More information can be found in the full paper by J. M. Gibbs et al. on page 2081 in Issue 19, 2018 (DOI: 10.1002/cbic.201800305). Cover art by Shyam Parshotam.

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.
