Our galleries are quietest on weekdays and weekend mornings. At busy times, particularly on Saturdays, you may need to queue for our temporary exhibitions.

We’re undertaking some research with website visitors to learn more about how people find access-related information provided by museums. This survey shouldn't take longer than 10 minutes to complete. Thank you for your time!

A large single sheet of graph paper (approx. 27" x 57", found folded to A4 size) showing "FC" numbers.

In 1961, Crick, Sydney Brenner, Leslie Barnett and R J Watts-Tobin began a series of genetic experiments designed to investigate the general nature of the genetic code by inducing mutations in the DNA of bacteriophage T4, a virus that infects bacteria. Following an initial series of experiments (published as Crick et al, 1961, "General nature of the genetic code for proteins"), sustained detailed work continued to provide a more comprehensive genetic map, eventually published in Crick et al, 1967, "Phase-shift and other mutants in the first part of the rIIB cistron of bacteriophage T4," Phil Trans Roy Soc, 252 (780), 487-560.

The large single sheet of graph paper that comprises this file is a working draft document from this more comprehensive mapping exercise.

For background, see also Crick, What Mad Pursuit (1988), pp. 127-36, and Judson, The Eighth Day of Creation (1996), pp. 442ff.
