Abstract
The incorporation of U-C14-L-phenylalanine into acid-insoluble material and poly-L-phenylalanine following ultraviolet irradiation of polyuridylic-acid was examined. Irradiation of the polyuridylic-acid with doses of ultraviolet light from 24 - 72 x 104 ergs/mm2 resulted in a marked depression in C14.pnenylalanine incorporation and was accompanied by an increase in C14-serine uptake into both acid-soluble material as well as polyphenylalanine.Keywords
