In this letter, written at the beginning of Crick's twenty-year collaboration with the South African geneticist Sydney Brenner, Crick gave an account of recent developments in research personnel, techniques, and equipment at the Cavendish. Specifically, Crick mentioned his work on microsomal particles, fragments of endoplasmic reticulum, an ultramicroscopic organelle--a system of cavities bound by a membrane--that can be found in the cytoplasm of the cells of nearly all higher organisms. Certain microsomes bear large numbers of ribosomes, and are the place where the peptide chain is put together.
