Structure of RCΔ97. At the top is a HindIII map of the AD169 genome, with the region surrounding UL97 (coordinates 139495 to 142993) expanded below. The bottom diagram represents the insertion, with dotted lines showing the portion of the UL97 ORF that was replaced. Open arrow, the E. coli gpt gene under the control of the tk promoter; shaded arrow, the E. coli lacZ gene under the control of the rat β-actin promoter. The DNA probe used for the DNA blots is shown as a heavy solid bar.
