INTRODUCTION Recent molecular biological analyses of mitochondrial deoxyribonucleic acids (mtDNAs) and chloroplast deoxyribonucleic acids (chiDNAs) have revealed many interesting and unexpected and some totally unique features of these genomes. ThemtDNAs of unicellular organisms vary greatly in size, shape, and gene arrangement, with some of the genes having organiza-tions not previously observed in bacterial or eucaryotic genomes. By contrast, animal mtDNAs are strikingly uniform in structure and contain an extraordinary gene arrangement which permits maximum exploitation of their coding capacity. Similarly, the chIDNAs of unicellular eucaryotes are more variable in size and organization than the chlDNAs of vascular plants. Nevertheless, the organization and se-quence of many chlDNA genes are highly ho-mologous to the organization and sequence of bacterial genes, and some cloned chloroplast genes have even been expressed in Escherichia coli. Analyses of the amino acid coding sequences of organelle DNAs have yielded an even greater surprise. The genetic codes ofmtDNAs differ from those of all other organisms and even from each other. However, chiDNAs retain the universal code present in bacteria. These unique and varied characteristics have rekindled interest in the ongin and evolution of mitochondria and chloroplasts. Are these organ-elles highly evolvedendosymbionts (6, 253, 264, 389) which still retain remnants of their original DNAs and associated replication, transcription, and translation systems (154, 275-277, 309, 313, 315), or are they simply advanced procaryotic algae in which the energy production mem-branes have been elaborated and have trapped cellular DNA, enzymes, and ribosomes (5, 85, 201)?I have collated the data on organelle genomes available up to October 1981 and used these data to propose empirical generalizations and evolutionary relationships about organelle DNAs. The combined conclusions have been integrated into a scenario for the evolution of these unique and essential eucaryotic DNAs.
