Gene input function and its input dynamic range. The input function is defined as the normalized promoter activity at different signal concentrations. The black horizontal dashed lines mark the 10% and 90% promoter activity. The input dynamic range is the ratio R of input concentrations required for 90% and 10% of maximal output.
