TL;DR: It is proposed that most of the isolated RD1A mtDNA is present in large fishnets concatenanes; the unwinding restriction imposed on DNA of which the strands are plaited into a fishnet concatenate explains the restricted ethidium uptake.

TL;DR: The results confirm the previous conclusion that the mtDNA of RD1A mainly consists of perfect repetitions of a sequence of 300 nucleotides or less and leads to an underestimation of the molar C content of these DNAs by about 15 %.

TL;DR: The results suggest that Tetrahymena mtDNA is a circularly permuted collection of molecules and that initiation of DNA synthesis occurs at multiple sites on the molecule.

TL;DR: DNA-DNA hybridization showed that the 8-S DNA hybridizes predominantly with the light strand of mtDNA (like the E-strand of I★), in contrast, the labelled full-length strands hybridized mainly with the heavy strands.

TL;DR: The results rule out the possibility that this nuclear DNA fraction in primary embryonic cell cultures has an informational role, as it contains all rather than a selection of the information in the cell genome.
