Abstract
The cloning of DNA fragments is a fundamental aspect of molecular biology. Traditional DNA cloning techniques rely on the ligation of an insert and a linearized plasmid that have been digested with restriction enzymes and the subsequent introduction of the ligated DNA into Escherichia coli for propagation. However, this method is limited by the availability of restriction sites, which often becomes problematic when cloning multiple or large DNA fragments. Furthermore, using traditional methods to clone multiple DNA fragments requires experience and multiple laborious steps. In this protocol, we describe a simple and efficient cloning method that relies on homologous recombination in the yeast Saccharomyces cerevisiae to assemble multiple DNA fragments, with 30-bp homology regions between the fragments, into one sophisticated construct. This method can easily be extended to clone plasmids for other organisms, such as bacteria, plants, and mammalian cells.

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
