Restriction analysis of DNA labelled with [32P]dCTP in an in vitro replication system with isolated nuclei from early S phase cells showed preferential labelling of restriction fragments derived from mitochondrial DNA (mtDNA) by a replication machinery distinct from that responsible for bulk nuclear DNA replication. Use of restriction nucleases with one recognition site in mtDNA gave rise to 16.5 kbp long fragments corresponding to full-length linearized mtDNA, indicating the presence of intact mtDNA in the isolated cell nuclei. Incorporation of dNTPs into mtDNA was not restricted to the S phase of the cell cycle. We were unable to increase the labelling of mtDNA by the addition of purified mitochondria or mtDNA to the nuclear replication system. These and other results presented is evidenced that the presence of mtDNA in the isolated nuclei was not due to uptake during preparation, thus indicating its presence in the cell nucleus in vivo.
