Non-invasive mRNA stability measurements reveal that transcript lifetime is governed by a competition with translation initiation on a transcriptome-wide level.
Relying on RNA fragments derived from degradation or partial template copying, non-enzymatic primer extension with strand displacement offers a novel and prebiotically plausible approach to RNA self-replication.
Manipulation of the E. coli translation machinery sheds new light on evolutionary constraints and optimization strategies for bacterial translation and growth.

Live-cell imaging, genetic analysis and electron cryomicroscopy identify structural motifs involved in the differential assembly of Pol I-Rrn3 complexes and Pol I homodimers in response to nutrient availability.

Bidirectional promoter activity, which is inherent to the promoters of selection cassettes used for genome editing, causes divergent transcription that can disrupt expression of genes neighboring cassette insertion sites, causing potent off-target effects.
The retarding effect of a ribosome-bound internal ribosome entry site on eukaryotic protein synthesis is largely overcome following translocation of tripeptidyl-tRNA.
Human plasma contains protein-protected mRNA fragments, myriad repeat RNAs, and novel intron RNAs, including a family of structured full-length excised introns, some corresponding to mirtron pre-miRNAs and agotrons.
