Herpes viruses. Coloured Transmission Electron Micrograph (TEM) of clusters of herpes viruses infecting a cell. Cross-sections of individual virus particles (seen outside the cell, at top of image) reveal an inner core of genetic material (DNA, yellow) encased in a blue protein coat. The cell (brown, bottom right) has been infected by several viruses. Herpes viruses reproduce by binding to the wall of a host cell and injecting their own DNA into it. The viral DNA hijacks the cell, turning it into a virus-making machine. Herpes viruses commonly cause human diseases such as chickenpox, glandular fever, cold sores, and shingles.
