Herpes virus is a typical nuclear DNA virus whose nucleocapsids are assembled in cell nuclei. However, it was found in the past few years that duck plague virus (a duck herpes virus) and herpes simplex virus can be assembled in the cytoplasm while being assembled in the nuclei as well. This phenomenon is quite different from the classical virology, but the reports concerning it are few. Much less is known abeut the mechanism of cytoplasmic morphogenesis.
