Analyses of genomes have allowed researchers to determine that some cells have very small genomes. If you were asked to predict which organisms are likely to have smaller genomes than others, which option below would be MOST likely? A. Bacteria that live in plant hosts are likely to have smaller genomes than those that live in animal hosts as it takes a smaller variety of metabolic processes to survive in an animal host. B. Although less is known about Archaea than about Bacteria as fewer species have been studied, it is likely that Archaea have smaller genomes on average than Bacteria as they have fewer metabolic needs. C. Bacteria that are endosymbionts, living within a host, can survive with smaller genomes than free-living Bacteria because they can rely on their host for many of their needs. D. Protists generally have had smaller genomes than Bacteria because Bacteria have such large amounts of noncoding DNA.
