After a decade of dominance by recombinant DNA technology, the field of molecular and cell biology is witnessing a renewed interest in techniques and approaches that are not driven by DNA acrobatics. In hindsight, this is an inevitable outcome. Deoxyribonucleic acid is not the master; it is only a storage house. If one wishes to know how cells work, the secret is not to be found in DNA, but rather in everything outside DNA. Science based on DNA is useful but does not itself solve the problem. It is most fortunate that at the height of the DNA phenomenon, there remain scientists who continue...
