The varicella zoster virus (VZV) is a form of the herpes virus that is responsible for producing chicken pox in children and shingles in adults. It is a viral infection, and the genetic material inside of VZV is DNA. The DNA in the VZV virus contains about 125,000 base pairs, making the genetic makeup of the virus much smaller than a typical animal cell and certainly much simpler than a human cell. The genome (or the genetic sequence of the DNA), is similar to the herpes simplex virus, or the sexually transmitted disease that is more commonly associalted with the term herpes. A virus invades a healthy cell and injects its viral DNA into the cell to allow it to replicate and destroy the healthy cell in the process.
