Fig. 3. Mechanism of CPD recognition by transcribing Pol II.
Schematic representation of RNA extension in complex A. The
initial RNA (top) corresponds to the nonextended RNA of scaffold
A. The translocation barrier and the translocation block are
indicated with a dashed and a solid horizontal line,
respectively. The artificial situation leading to lesion bypass
(Fig. 2E) is depicted at the bottom.
