Supplemental Figure 5: Impact of baseline expression level on protein concentration noise dependency with the division rate for <i>P</i> proteins from Division rate, cell size and proteome allocation: impact on gene expression noise and implications for the dynamics of genetic circuits BertauxFrançois MargueratSamuel ShahrezaeiVahid 2018 The analysis of Figure 4 is repeated for various baseline expression levels, obtained by scaling up the reference transcription rate, translation rate, or both. As transcription rate increases, intrinsic noise decreases, and the protein concentration noise decreases. The translation rate has a lower impact than transcription rate as mRNA noise dominates.
