In E. coli, a cluster of three genes called the lac (promoter/repressor/operator / operon) produce enzymes
that break apart lactose. To the side of the genes is a region called the (promoter_/repressor/ operator
operon), where RNA polymerase binds, and another region called the (promoter/repressor/ operator /
operon), where the lac repressor binds.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
