Let's say that you're a scientist trying to analyze newly sequenced bacterial DNA genomes from an environmental sample of rainforest soil, and your first task is to organize all of the genomes you find into a phylogenetic tree. If you couldn't use the 16S rRNA gene sequence to create the tree, which of these alternative genes would work best for your task of creating a tree for all the bacteria in your sample? O The first gene in the histidine biosynthesis pathway The gene for DNA polymerase core enzyme The first gene in the LPS synthesis pathway The gene for Bacteriochlorophyll A

A bacterial culture that has been pretreated with penicillin to inhibit its peptidoglycan synthesis is split and put into solutions of various concentrations. The same is done with a control culture with no prior penicillin exposure. Which condition is likely to demonstrate the biggest difference in outcomes between the control culture and the experimental culture? O Placing the cultures into a hypertonic solution Placing the cultures into a hypotonic solution O The control and experimental cultures should show you the same results in every condition O Placing the cultures into an isotonic solution
