Direct Evidence for Nuclear Synthesis of Cytoplasmic Ribose Nucleic Acid.
The question of the biosynthetic relationship of nuclear and cytoplasmic ribose nucleic acid (RNA) has received much attention in recent years. Interest has been focused on this problem by current speculation on the transmission of genetic specificity from desoxyribose nucleic acid (DNA) to cytoplasmic components. It has been suggested that RNA could serve as a receptor of a "code" from the DNA...

Nuclear Synthesis of Cytoplasmic Ribonucleic Acid in Amoeba proteus
The enucleation technique has been applied to Amoeba proteus by several laboratories in attempts to determine whether the cytoplasm is capable of nucleus-independent ribonucleic acid synthesis. This cell is very convenient for micrurgy, but its use requires a thorough starvation period to eliminate the possibility of metabolic influence by food vacuoles and frequent washings and medium renewal ...
متن کاملCytoplasmic Synthesis of Nuclear Proteins
The synthesis of cytoplasmic and nuclear proteins has been studied in HeLa cells by examining the amount of radioactive protein appearing in the various subcellular fractions after labeling for brief periods. Due to the rapid equilibration of the amino acid pool, the total radioactivity in cytoplasmic protein increases linearly. The radioactivity observed in the cytoplasm is the sum of two comp...
متن کاملNucleic Acid Synthesis
INTRODUCTION Synthesis in the field of nucleic acids has been a major and continuing interest in my laboratory ever since we knew the structures of the nucleic acids. Clearly the foundations of synthetic work in the nucleotide field were laid by the prolonged and intensive efforts of Professor Todd's laboratory (Cambridge, England) and it was my good fortune to be associated with this laborator...
