Linear mitochondrial genomes: 30 years down the line.

Author information

Department of Biochemistry, Faculty of Natural Sciences, Comenius University, Bratislava, Slovakia.


At variance with the earlier belief that mitochondrial genomes are represented by circular DNA molecules, a large number of organisms have been found to carry linear mitochondrial DNA. Studies of linear mitochondrial genomes might provide a novel view on the evolutionary history of organelle genomes and contribute to delineating mechanisms of maintenance and functioning of telomeres. Because linear mitochondrial DNA is present in a number of human pathogens, its replication mechanisms might become a target for drugs that would not interfere with replication of human circular mitochondrial DNA.
