Defend and explain how FtsZ-type proteins being found in mitochondria and chloroplasts strengthens or weakens the endosymbiosis theory
What will be an ideal response?
Answer: The protein FtsZ, encoded by the gene ftsZ, is specifically involved in prokaryotic cell division. FtsZ-like proteins identified in mitochondria and chloroplasts suggests the FtsZ-encoding gene was first present in prokaryotes and that these two organelles were subsequently developed and maintained in Eukarya. Ultimately this corroborates the ideas of the endosymbiotic theory and seemingly links chloroplast and mitochondrial origins to prokaryotes.
