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