1. A method for determining a length of a protein filament residing on a DNA-molecule, the method comprising steps of:
receiving light from the DNA-molecule hosting one or more optically active entities at at least one part of the DNA molecule not hosting the protein filament using a light-sensitive system, wherein the optically active entities cause light emission from said at least one part, and
the light-sensitive system outputting a signal based on the received light, and
determining a light value based on the output signal, the light value indicating an amount of light from the host structure being incident on the light-sensitive system, and
determining on the basis of the light value the length of the protein filament.
