Question

Quizplus · Accepted Answer

The theory of endosymbiosis suggests that mitochondria originated from free-living bacteria that entered into a symbiotic relationship with early eukaryotic cells. Therefore, mitochondrial ribosomal genes are expected to share similarities with bacterial ribosomal genes due to their common ancestry. Additionally, since all plants and trees are part of the eukaryotic domain, their mitochondrial ribosomes would also share similarities across different species, reflecting their shared evolutionary history.
