Trajectory of transcription from various models.

<p>Plots of N mRNA versus time with linear genome: (A) Initially all polymerases are in solution with D_sl = 0, R = 500, K_off = 10⁻⁵/s (B) same as (A) except K_off = 10⁻¹/s. (C) Transcription through sliding facilitated Polymerase release with R = 500, D_sl = 10⁴ nm²/s, K_off = 10⁻⁵/s. (D) Transcription through sliding non-colliding polymerases with R = 1, D_sl = 10⁴ nm²/s, K_off = 10⁻⁵/s.
