Unformatted text preview: symbiotic Theory Evidence A number of antibiotics (e.g., streptomycin and ) that act by blocking protein synthesis in bacteria also block protein synthesis within mitochondria and chloroplasts. They do not interfere with protein synthesis in the cytoplasm of the eukaryotes. The Endosymbiotic Theory Evidence Conversely, inhibitors (e.g., diphtheria toxin and cycloheximide) of protein synthesis by eukaryotic ribosomes do not -- sensibly enough -- have any effect on bacterial protein synthesis nor on protein synthesis within mitochondria and chloroplasts. The Endosymbiotic Theory Evidence The antibiotic rifampicin, which inhibits the RNA polymerase of bacteria, also inhibits the RNA polymerase within mitochondria. It has no such effect on the RNA polymerase within the eukaryotic nucleus. The Hierarchy of Taxonomic Organization
