Extended Data Fig. 6: CTD length impacts free RNAPII anisotropy.

a, Brownian simulations indicate substantial apparent anisotropy for mean displacement longer than 350 nm (n = 100 resamplings; mean value ± s.d.). b, Apparent anisotropy due to nuclear confinement in small yeast nucleus. c, CTD length increase leads to an elevation in f180/0 trend (n = 100 resamplings; mean value ± s.d.). Source numerical data are available in source data.
