Which of the following is the best evidence for a three-domain system ? A) There are three distinctly different Gram reactions B) There are three distinctly different types of nuclei C) Nucleotide sequences in ribosomal RNA vary between all three domains D) There are three distinctly different sets of metabolic reactions, The best evidence for the three domain system is Sensitivity to Antibiotics Explanation: The three domains of life includes: Archaea – oldest known domain, ancient forms of bacteria. Bacteria – all other bacteria that are not included in the Archaea domain. Eukarya – all the organisms that are eukaryotic or contain membrane-bound organelles and nuclei.
