In the 1930s, cell biologists had surmised that the greatest part of RNA was localized in the cytoplasm and that there was a correlation between the amount of RNA and the protein synthesizing capacity of the cell. In the 1940s, Brachet and Caspersson established unequivocally this correlation with materials as diverse as the root tips of Allium cepa, imaginal disks of Drosophila larvae, secreting pancreatic cells and silk glands from the silkworm and with various methods such as specific dying techniques, specific nucleases and spectrophotometric methods on thin tissue slices.
