(Phys.org)—Gene expression plays a central role in the orchestration of virtually all cellular processes. While inducible promoters have proven invaluable in understanding regulatory networks by modifying gene expression ...
(Phys.org)—As an animal develops from an embryo, its cells take diverse paths, eventually forming different body parts—muscles, bones, heart. In order for each cell to know what to do during development, it follows a ...
