Post-Transcriptional Noise Control. [PDF]

open access: yesBioessays, 2019
Recent evidence indicates that transcriptional bursts are intrinsically amplified by messenger RNA cytoplasmic processing to generate large stochastic fluctuations in protein levels. These fluctuations can be exploited by cells to enable probabilistic bet‐hedging decisions.
