What role does gel electrophoresis play in identifying a specific gene? O It binds the gene of interest with probes It separates DNA fragments It kills all the cells that have not taken up the gene of interes It cuts out the gene of interest in DNA at specific points.​

separates fragments of DNA that have different lengths.

Explanation:

The particles that are contains in the gel interrupt the path of the DNA fragments when they are attracted by the electric current, so the longest ones are the ones nearest the origin(where the sample was placed before the electrophoresis) and the smallest ones are the ones at the end of the gel.

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.
