Figure 17.2 the Accompanying Figure Above Shows the Distances Between Genes in Genes

Figure 17.2
The accompanying figure above shows the distances between genes in minutes. Assume that the time listed between two genes corresponds to the transfer time of the first of the two genes in the pair. Use the figure to answer questions 29-32.
The genetic map shown in the figure was generated by identifying transferred genes after ____.

A) allowing transformation to proceed for varying amounts of time
B) allowing conjugation to proceed for varying amounts of time ​
C) bacterial cells were infected by various bacteriophages ​
D) replica plating of E. coli auxotrophs ​
E) allowing transduction to proceed for varying amounts of time ​
