Classify the statements below as to whether they describe mitochondria, chloroplasts, or both. Cannot live independently because they require some proteins and RNAS encoded by nuclear genes. In some species, some codons specify a different amino acid than is specified in the universal genetic code. Translation is inhibited by chemicals known to inhibit bacterial translation, such as chloramphenicol Carry genes for some of the enzymes of photosynthetic electron transport. rRNA gene sequences are most similar to cyanobacteria. May have arisen...

Endosymbiosis is an evolutionary theory that explains the origin of eukarvotes and suggests a specific order in which this might have occurred. Ancestral cells enguited and then began to use the metabolic processes of the smaller cells. Based on shared core processes and features, which statement most accurately describes the order, the theorY and the evolutionary implications for all organisms within domain Eukarya? OAll ancestral eukaryotes would have most likely consumed a nucleus-ike prokaryote that eventually became the eukaryotic nucleus....
