Abstract
Phosphoramidite reagents (linker phosphoramidites) containing a cleavable 3'-ester linkage between the nucleoside and the phosphoramidite group can be used to attach the first nucleoside to a solid-phase support. Inexpensive underivatized supports such as LCAA-CPG can then be used as universal supports for oligonucleotide synthesis. No modifications to synthesis coupling conditions and no 3'-dephosphorylation are required. Only oligonucleotides with terminal 3'-OH ends are produced. Phosphoramidites containing both a succinate and a sulfonyldiethanol linkage are particularly useful and create oligonucleotides with both a 3'-OH and 5'-phosphate. In addition, by using these reagents, one oligonucleotide sequence can be added onto the 5'-end of another (tandem synthesis) to produce a string of multiple oligonucleotides linked end-to-end. Deprotection releases the oligonucleotides from each other to yield a mixture of oligonucleotides. This approach is particularly useful for making pairs of PCR primers or both strands of a double-stranded sequence in a single operation.

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.
