Interpret the genomic content of mitochondria in relation to their evolution. How is mitochondrial evolution more complicated than expected?
What will be an ideal response?
Answer: Some mitochondria contain accessory plasmids in addition to chromosomal DNA. The shapes of mitochondrial genomes are not all the same; some are linear and others are circular. These fundamental differences in mitochondrial genomes further complicate even basic comparative analyses. Some mitochondrial genes have also been transferred to the nuclear genome.
