Correction for Tadigotla et al., Thermodynamic and kinetic modeling of transcriptional pausing

biophysics. For the article “Thermodynamic and kinetic modeling of transcriptional pausing,” by Vasisht R. Tadigotla, Dáibhid Ó Maoiléidigh, Anirvan M. Sengupta, Vitaly Epshtein, Richard H. Ebright, Evgeny Nudler, and Andrei E. Ruckenstein, which appeared in issue 12, March 21, 2006, of Proc. Natl. Acad. Sci. USA (103, 4439–4444; first published March 13, 2006; 10.1073/pnas.0600508103), the authors note that on page 4444, in the first line of the left column, “P_thresh = 0.95 (Bai I)” should have read “P_thresh = 0.05 (Bai I).” In addition, on page 4444, in lines 10 and 11 of the left column, “unreasonably high P_thresh of 0.9 (Bai III)” should have read “unreasonably low P_thresh of 0.1 (Bai III).”
