Mean GC Content of Selected HSV-1 Gene Groups^a

Gene group	Mean %GC ± SD	P valueb
Essential Non-essential	67.3 ± 3.9 (n=34) 66.5 ± 4.3 (n=38)	0.55
Core Non-core	66.7 ± 2.8 (n=43) 67.3 ± 5.4 (n=38)	0.39
Beta kinetic class Gamma kinetic class	65.5 ± 2.8 (n=13) 66.5 ± 4.3 (n=38)	0.87
All UL All US	66.6 ± 3.1 (n=58) 65.2 ± 1.4 (n=12)	0.91

^aSource: Essential, Non-essential, Beta (early) kinetic class, Gamma (late) kinetic class: [7]; Core, Non-core: [3]; UL, US: GenBank NC_001806.

^bApplies to the hypothesis that the GC content of the two gene groups is different.
