||"[Researchers] investigated the properties of the ternary complex
of RNAP II at a T<>T [cyclobutane thymine dimer] in the template strand and the effect of the ternary complex on human excision nuclease."
||"The footprint of RNAP II stalled at the thymine dimer, obtained using DNase I, lambda exonuclease and T4 polymerase 3'>5'exonuclease, covers approximately 40 nt and is nearly symmetrical around the dimer." "[Researchers'] data show that
RNAP II makes a stable ternary complex at the T<>T site (t1/2~20 h) in which RNAP II covers ~40 nt around the dimer in a nearly symmetrical manner."
