This sculpture by British artist Abigail Fallis (b.1968) consists of 22 shopping trolleys in the shape of a double helix. The work was commissioned by a supermarket chain in 2003 on the 50th anniversary of American biologist James Watson and English physicist Francis Crick's discovery of DNA's double-helix structure, which was based on Rosalind Franklin's X-ray diffraction images of DNA. Their findings were fundamental to the understanding of muscular dystrophy. It is part of an art trail called The Line
