Question

Which of the following is INCORRECT evidence to support the endosymbiotic theory?

(a) Mitochondria are self-repeating bodies like microscopic organisms

(b) Mitochondria have their own particular DNA

(c) Mitochondrial ribosomes, and enzymes are similar to the bacteria

(d) Mitochondria and bacteria differ in size

I had been asked this question during a job interview.

Enquiry is from Mitochondria topic in section Cell Structure and Functions of Life Sciences

Answer 1

Right answer is (d) Mitochondria and bacteria differ in size

To explain I would say: Endosymbiotic theory had supported the fact that mitochondria have evolved in eukaryotes by the symbiotic association of bacteria. Mitochondria and bacteria differ in size is incorrect as the size of mitochondria and bacteria is approximately same.
