Fig. 5From: Genome-wide analysis of G-quadruplexes in herpesvirus genomesImmediate early genes have higher PQS densities compared to early and late genes. Bar graph showing average PQS densities in the regulatory regions (1000bp upstream of the start codon) of immediate early (IE) genes as compared to early (E) genes and late (L) genes. The number of full-length sequences studied for each virus is shown in parentheses. Among herpesviruses (HHV-1, HHV-2, HHV-3, HHV-5, HHV-8) the regulatory regions of IE genes had several fold higher PQS densities as compared to that of E genes or L genes (*P < 0.05)Back to article page
