DNA, RNA, and protein synthesis in mitochondria isolated from cerebral hemispheres, brain stem, and cerebellum of 10- and 30-day-old rats was measured. Synthesis of different macromolecules was affected by the respective mitochondrial specific inhibitors, showing a good level of purity of mitochondrial preparations. DNA and protein synthesis in 10-day-old rats was about 70% higher than in 30-day-old animals. In contrast, RNA synthesis did not decrease with age in all the regions examined.

Abstract
DNA, RNA, and protein synthesis in mitochondria isolated from cerebral hemispheres, brain stem, and cerebellum of 10- and 30-day-old rats was measured. Synthesis of different macromolecules was affected by the respective mitochondrial specific inhibitors, showing a good level of purity of mitochondrial preparations. DNA and protein synthesis in 10-day-old rats was about 70% higher than in 30-day-old animals. In contrast, RNA synthesis did not decrease with age in all the regions examined.File in questo prodotto:
