Rho-dependent terminators are defined by the need for addition of rho factor in vitro, and mutations show that the factor is involved in termination in vivo.

Nirenberg and Matthaei therefore concluded that the triplet codon UUU encodes phenylalanine, poly(C) proline (polyproline), polyadenylate, poly(A), encodes polylysine.
