Answer:
b. Many mitochondrial proteins are coded by cellular nuclear DNA.
Explanation:
According to the concept of endosymbiosis, eukaryotic organelles such as mitochondria and chloroplasts arose from symbiotic relationships between larger cells and smaller prokaryotes. These smaller prokaryotes were incorporated and lived within them. According to this concept, mitochondria originated when a larger cell engulfed an aerobic bacteria (most probably the purple bacteria) that lived in it. However, some of the proteins of the mitochondria are encoded by nuclear chromosomes. This dependence of mitochondria on nuclear DNA does not support the concept of endosymbiosis.
