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?
rRNA gene sequence and amino acid sequence of lipase
cell wall structure and physical appearance
reproductive rate and susceptibility to pesticides
entire genome sequence and protein expression data

The best characteristics for creating the phylogeny of the soil bacteria would be the entire genome sequence and protein expression data. This is because these data provide the most comprehensive and detailed information about the genetic composition and functions of the bacteria, allowing for a more accurate classification and phylogenetic analysis. The rRNA gene sequence and amino acid sequence of lipase can also be useful for phylogenetic analysis, but they may not provide as much information as the entire genome sequence and protein expression data. Cell wall structure and physical appearance, as well as reproductive rate and susceptibility to pesticides, may not be as reliable for creating a phylogeny as they may be influenced by external factors and environmental conditions.
