DNA folding

We were commissioned to build an exhibit for the Royal Society Summer Festival in 2017 by Weatherall Institute of Molecular Medicine. They'd got some clear ideas about how the challenge activity they wanted to illustrate their work, and experimented with a prototype with 'chromosome' strings which participants folded to link genes (paperclips) with activation sites (more paperclips) so that the cell might be a red blood cell, a white blood cell, or might not be viable.
