title: [DNA content of the mitochondria of the developing rat brain].
abstract: Studies have been made on the content of DNA in the mitochondria from the brain of 1, 5, 10, 15, 21, 60, and 400 days old rats. Isolated DNA preparations contained 7% of RNA and 3% of proteins. It was shown that the amount of DNA in 21- and 60-day rats is 4 times higher that than in newborn ones. DNA content of the mitochondria increases during the first 3 weeks of postnatal life of rats.
