PPT-Herpesviridae is the name of a family of enveloped, double-stranded DNA viruses with

Karposis sarcoma herpesvirus HHV8 HUMAN HERPESVIRUSES Virion Structure All herpesvirus virions have four structural elements Core The core consists of a single linear molecule of dsDNA in the form of a torus .

During the 1940s, biologists determined that the bases in DNA had a specific relationship:. the amount of adenine (A) was equal to the amount of . A virus must use cell processes to replicate. The viral replication cycle can produce dramatic biochemical and structural changes in the host cell, which may cause cell damage. These changes, called cytopathic (causing cell damage) effects, can change cell functions or even destroy the cell.
