Effect of magnesium ions on the resistance of pRNA 3WJ to urea denaturation, assayed by 15% PAGE gels with (A) 2 mM EDTA and (B) 5 mM MgCl2. (Lane 1) Single RNA oligo b3wj; (lane 2) sample annealed from two oligos a3wj and b3wj; (lane 3) 3WJ assembled from three oligos a3wj, b3wj, and c3wj; and (lane 4) DNA ladder.
