Resolving functional mRNA units clarifies the decay landscape of the bacterial transcriptome
The lifetime of an mRNA is a critical determinant of protein output. In bacteria, mRNA decay is commonly assayed by arresting transcription and quantifying the remaining transcripts. However, the resulting decay time-courses often deviate from first-order kinetics, suggesting a fundamental gap in our understanding of mRNA turnover. Here, we demonstrate that this kinetic inconsistency arises from…
