Figure 1.
Comparison of the VZV and HSV genomes. The VZV genome (first rows) contains unique long (UL) and unique short (US) regions flanked by terminal long (TRL), terminal short (TRS), internal long (IRL), and internal short (IRS) repeats. VZV genes (second rows) and HSV genes (third rows) are shown by numbers. VZV or HSV genes that do not have homologs in the corresponding virus circled. The HSV genome contains UL and US regions, and TRL, TRS, IRL, and IRS repeats (fourth rows). Modified from Cohen 1999, with permission.
