Question

multiple choice question. dna analyses indicating a close relationship between mitochondria and proteobacteria and between chloroplasts and cyanobacteria support the
o rna world hypothesis.
o endosymbiosis theory.
o theory of natural selection.
o hydrothermal vent model.

Explanation:

The endosymbiosis theory posits that mitochondria and chloroplasts in eukaryotic cells originated from free - living prokaryotes (mitochondria from proteobacteria and chloroplasts from cyanobacteria). DNA analyses showing close relationships support this theory. The hydrothermal vent model is about the origin of life in hydrothermal vents. The theory of natural selection is Darwin's theory about the survival and reproduction of organisms. The "RNA world" hypothesis suggests that RNA was the first genetic material.

Answer:

C. endosymbiosis theory
