NE and rHMG-2 change the optimal DNA length for cyclization. Fractions of DNA probes cyclized in 2-min ligation reactions (from Fig. 3 and 4) are plotted as a function of probe length. Curved templates are indicated with triangles, while all other probes are indicated with circles. (A) Naked DNA. (B) DNA in the presence of NE. (C) DNA in the presence of rHMG-2.
