Discussion
Which of the following theory is supported by the genomic sequence of the obligate intracellular parasite Rickettsia prowazekii ?
Answer: C
Correct answer: Mitochondria have evolved from endosymbiotic bacteria
Rickettsia prowazekii is an obligate intracellular parasite whose genome is small and whose retained genes for aerobic energy generation resemble those of mitochondria more closely than any other bacterium’s. That similarity is strong evidence that mitochondria descend from an alpha-proteobacterial endosymbiont.
