Abstract
This article outlines a method for investigating the formation and function of potentially prebiotic complex coacervates, as primitive compartments, generated through electrostatic interactions between anionic nucleic acids and cationic peptides. The Basic Protocols specifically detail the experimental procedures for conducting nonenzymatic RNA primer extension reactions using 2-aminoimidazole-activated ribonucleoside 5'-O-monophosphates in the presence of these coacervates (e.g., composed of specific "host" DNA/RNA sequences and short polyarginine peptide partners). Designed to be accessible to researchers with limited prior experience in coacervate systems, this step-by-step guide provides a practical framework for probing prebiotic polymerization processes, an area of importance in the study of the origins of life. © 2025 The Author(s).

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 it
