an Immuno-Embryological Study of the Chick Lens.

Abstract

Although during the last decades considerable information has been obtained concerning the nature of biochemical processes during development (Needham, 1942; Brachet, 1947), our knowledge with regard to the synthesis of new protein molecules, the essentialness of such molecules in determining the shape and function of a cell and organ, the reduplication of existing molecules during growth, and the localization of specific molecules in organ primordia, is far from satisfactory
