The definition of a virus as a DNA or RNA virus, based on its genetic material, is now on shaky ground thanks to the findings of Bresnahan and Shenk in the 30 June Science. Using a gene array, they find that particles of human cytomegalovirus (HCMV), a large DNA virus, contain four different mRNAs (Science 2000, 288:2373-2376). The mRNAs are derived from one immediate-early gene, two early genes and one late gene, but translation from at least one of the packaged mRNAs peaks before there is dete
