I have measured the metabolism of tRNA$ sp{ rm Asn}$ in Friend cells undergoing erythroid differentiation, using an assay exploiting the tRNA$ sp{ rm Asn}$ gene's ability to specifically hybridize tRNA$ sp{ rm Asn}$. The concentrations of tRNA$ sp{ rm Asn}$ measured as a proportion of the total tRNA population (relative concentration) decreased until day 3 post-induction, and then increased on day 4. The relative concentrations of tRNA$ sp{ rm Asn}$ are influenced by tRNA$ sp{ rm Asn}$ having lower turnover rate in comparison to the total tRNA population, and by the relative rate that labelled, newly synthesized tRNA$ sp{ rm Asn}$ accumulates in vivo. The rate of tRNA$ sp{ rm Asn}$ synthesis in nuclei isolated from Friend cells at different times during differentiation also fluctuates. This fluctuation may reflect changes in RNA polymerase III activity in these isolated nuclei.
