The Distribution of Nucleic Acids in rat Eggs in Fertilization and Early Segmentation I. Studies on Living Eggs by Ultraviolet Microscopy

Abstract

Observations have been made on the absorption of ultraviolet radiation at 260� mft by living rat eggs, as full-grown oocytes and during fertilization and early' cleavage. Precautions have been taken to permit the results to be interpreted in terms of nucleic acid concentrations.
