Deletion Experiments of E

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.
