We investigate the hypothesis that, in Escherichia coli, while the concentration of RNA
polymerases differs in different growth conditions, the fraction of RNA polymerases free for …

Closely spaced promoters in tandem formation are abundant in bacteria. We investigated
the evolutionary conservation, biological functions, and the RNA and single-cell protein …

Dennis Salahub has contributed to several scientific areas. Likely, one of the lesser known
contributions is the one on the study of the kinetics of gene expression in prokaryotes, which …

Many genes are spaced closely, allowing coordination without explicit control through
shared regulatory elements and molecular interactions. We study the dynamics of a …

Recent advances in microscopy imaging technology have allowed the characterization of
the dynamics of cellular processes at the single-cell and single-molecule level. Particularly …
