A sample of bacteria is collected from soil in a field that was recently treated with pesticides. The bacteria are classified, and a phylogeny is built to illustrate the soil bacteria diversity. What kinds of characteristics would be BEST for creating this phylogeny?

A. rRNA gene sequence and amino acid sequence of lipase.

B. Cell wall structure and physical appearance.

C. Reproductive rate and susceptibility to pesticides.

D. Entire genome sequence and protein expression data.

D. Entire genome sequence and protein expression data.

For creating a phylogeny to illustrate soil bacteria diversity, it would be best to use whole genome sequencing data and protein expression data. These provide a comprehensive view of the genetic makeup and functional characteristics of the bacteria, allowing for a more accurate classification and comparison of different bacterial species. rRNA gene sequences and amino acid sequences of specific enzymes like lipase can also be useful, but they may not capture the full genetic diversity present in the bacterial population. Cell wall structure and physical appearance are more general characteristics that may not provide enough resolution for a detailed phylogenetic analysis. Reproductive rate and susceptibility to pesticides are important factors in the context of pesticide treatment, but they may not be sufficient for building a phylogeny.
