FIGURE 2. (A) Head-on collisions between the replication fork and transcription complexes. Because the DnaB fork helicase (green) translocates on the lagging strand template, head-on collisions with RNAP (red) blocks fork progression. (B) Codirectional collisions. DnaB fork helicase can proceed unimpeded, but fork unwinding can stabilize extensive R-loops (RNA/DNA hybrids) behind RNAP.
