## Abstract Slices of cerebral hemispheres, brain stem, and cerebellum from rats 5β30 days old were used for in vitro incorporation of [methylβ^3^ H] thymidine and [6β^14^ C] orotic acid into DNA and RNA, respectively. The rates of DNA and RNA synthesis decreased markedly during development, with t

β¦ Synopsis
DNA-polymerases a and f3 were studied in neuron and glial cells of mouse during developing and aging brain. Maximum activity of a-enzyme was found to be prenatal, though a very low but significant level could be detected in aging brain. Furthermore, this pattern was found to be dependent upon cell types that shift in peak activity just before birth in glial cells in contrast to neurons. DNA-polymerase-f3 remained high throughout the period studied though a second peak of activity was also observzd at day 30 in both cell types, suggesting a possible role in DNA-replication in addition to DNA-repair. It was found that f3-enzyme from glial cells behaves differently than the same enzyme from neurons.
