Figure 3

Genomic structure of M24-BAC virus and pM24-BAC plasmid DNA. HindIII restriction analysis of M24-BAC virus DNA (left panel) and pM24-BAC plasmid DNA (right panel) is shown. Closed arrowhead: 9.4 kb HindIII fragment of d120 (containing ICP6 region), Open arrowheads: 15 kb and 2.2 kb HindIII fragments generated by insertion of the BAC sequences. A band present in M24-BAC digest just above the closed triangle is the submolar terminal restriction fragment (9.8 kb) derived from the short terminal repeat. This band is overlapped by the 9.4 kb restriction fragment of d120 and absent from pM24-BAC. The restriction pattern of pM24-BAC indicates that this clone contains both the UL and US sequences of HSV genome in the forward orientation. Other bands present in the M24-BAC digest but not in pM24-BAC are submolar terminal fragments or L-S junction fragments derived from other isomeric forms of virus genome.
