Thus, disrupted cells or their isolated fractions were reported to be capable of synthesizing proteins (Borsook 1950; Winnick 1950a, 1950b; Siekevitz and Zamecnik 1951; Siekevitz 1952; Peterson and Greenberg 1952; Khesin 1953; Gale and Folkes 1954). In the meantime, ribonucleoprotein particles were observed and identified in cells (Palade 1955) and then isolated from cells and studied with respect to their physicochemical properties (Chao and Schachman 1956; Ts'o et al. 1956; Peterman and Hamilton 1957; Tissieres and Watson 1958; Tissieres et al. 1959; see also papers in Roberts 1958).

The word "ribosome" was proposed to designate the protein-synthesizing ribonucleoprotein particles.
