Abstract

IN a previous communication we have compared the relative efficiency of various proteins, peptides and free amino-acids as precursors of chick embryonic proteins1. From these studies we concluded that during the early stages of development the preferred precursor was yolk protein (rather than peptides or amino-acids) and that the pathway of synthesis of chick embryonic protein probably proceeded via a stage involving amino-acid derivatives (possibly amino acyl adenylates2 or, more likely, amino-acids linked to the terminal adenosine residues of polyribonucleotides3–6).
