When Comparing the Genomes of a Bacterial Parasite Versus a Free-Living

When comparing the genomes of a bacterial parasite versus a free-living, nonparasitic bacterium, one expects to find that ________.

A) the proportion of G-C base pairs will be significantly higher in the parasite
B) there is no homology between the free-living and parasitic bacteria
C) there will be a higher proportion of genes of unknown function in the parasite
D) the parasite will have acquired a smaller proportion of its genes through lateral gene transfer
E) the parasite will have a smaller genome
