Abstract
The rate of RNA synthesis in eight regions of the root apex of Zea mays has been determined. Cells of the quiescent centre have a lower level of RNA synthesis than any other region studied. The level of RNA synthesis appears to be a function of the position of the cell in the apex. All the newly synthesized RNA detected in chromatin and cytoplasm can be accounted for by synthesis in the nucleolus and subsequent transport to these compartments. Newly synthesized RNA appears in the three compartments at different rates depending on the location of the cell.Keywords
