Organization and evolution of the mitochondrial genome of yeast.
The mitochondrial genome of yeast (S. cerevisiae or S. carlsbergensis) appears to be formed by 60-70 genetic units, each one of which is formed by (1) a GC-rich sequence, possibly having a regulatory role; (2) a gene, and (3) an AT-rich spacer, which probably is not transcribed. Recombination in this genome appears to underlie a number of important phenomena. The organization of the mitochondrial genome of yeast and these recombinational events are discussed in relationship with the organization and evolution of the nuclear genome of eukaryotes.
