Figure 2

P22 DNA packaging genes and pac site.Gene numbers are indicated within the boxes denoting the genes above. Below is a densitometer scan of an electrophoresis gel of NruI generated P22 packaging series left-end fragments. The peaks indicate the locations and relative frequencies at which ends are generated for initiation of DNA packaging series at the native pac site. The horizontal black box indicates the size and location of the pac site.34 This figure is modified from Figure 4 of Casjens et al.30
