Like other herpes viruses varicella is an enveloped DNA virus.
<span>Varicella-zoster virus is a type of herpes virus which infect humans also called chickenpox virus, varicella virus, zoster virus, and human herpesvirus type 3 (HHV-3). Its genome is a linear duplex DNA molecule, it multiplies in the lungs and after the primary infection, it goes dormant into neural cells where it can be reactivated and cause neural diseases.</span>
The chromosome is the one that carries the genetic information. The gene is the basic unit of heredity, meaning, this is the one that we carry from our parents. Genome is the collection of genes that is present in an organism. Therefore, if we arrange this from simplest to the most complex, the arrangement would be GENE, CHROMOSOME, GENOME.
