In a new Nature Communications study, researchers have explored the construction of genetic circuits on single DNA molecules, demonstrating localized protein synthesis as a guiding principle for dissipative nanodevices, offering ...
Environment is not the only factor in shaping regulatory patterns—and it might not even be the primary factor, according to a new Rice University study that looks at how cells' protein networks relate to a bacteria's genome.
