During the development of the vertebrate lens it acquires a low RNA content. Evidence indicates the persistence of a low molecular weight RNA while rRNA is depleted. This low molecular weight RNA has been characterized by chromatography, centrifugation and electrophoresis. Data indicate that it is primarily tRNA with small amounts of 5-S RNA. The persistence of the low molecular weight component is shown to be due to the selective retention of tRNA and not the accumulation of rRNA breakdown products. The degradation of rRNA is shown to occur on sedimentable ribonucleoprotein particles.
