Photograph 51, now playing at the Ensemble Studio Theatre, dramatizes the personal side of the scientists who determined that the structure of Deoxyribonucleic acid, or DNA, was a spiraling polymer of nucleic acids that we all know now as the double helix. Rosalind Franklin, who is at the center of the drama, was the first to capture a reliable image of it, although it was her colleagues who won the Nobel Prize for determining its structure in 1962. Written by Anna Ziegler and directed by Linsay Firman, the play runs Mondays and Wednesday through Saturdays at 7 p.m., with matinees on the weekends, now through November 21st. Tickets are $30, $15 for students and seniors.
