Deletion Experiments of E

question 4

Multiple Choice

Deletion experiments of E. coli have determined the minimal set of metabolic pathways. When these pathways were compared to a closely related species, W. glossinidia, an endosymbiotic organism that obtains resources from its host, researchers found that

• A) W. glossinidia had fewer metabolic pathways.
• B) E. coli was more specialized and had fewer metabolic pathways.
• C) the gene sets match perfectly.
• D) the genomes were not comparable.
