A DNA virus is a virus that has DNA as its genetic material and replicates using a DNA-dependent DNA polymerase. A virus (from the Latin virus meaning Toxin or Poison) is a sub-microscopic infectious agent that is unable Deoxyribonucleic acid ( DNA) is a Nucleic acid that contains the genetic instructions used in the development and functioning of all known Genetic material is used to store the genetic information of an organic life form A DNA Polymerase is an Enzyme that assists in DNA replication. The nucleic acid is usually double-stranded DNA (dsDNA) but may also be single-stranded DNA (ssDNA). A nucleic acid is a Macromolecule composed of chains of monomeric Nucleotides In Biochemistry these Molecules carry Genetic information DNA viruses belong to either Group I or Group II of the Baltimore classification system for viruses. The Baltimore classification is a Virus classification system which groups Viruses into families depending on their type of Genome ( DNA Single-stranded DNA is usually expanded to double-stranded in infected cells. Although Group VII viruses such as hepatitis B contain a DNA genome, they are not considered DNA viruses according to the Baltimore classification, but rather reverse transcribing viruses because they replicate through an RNA intermediate. A reverse transcribing virus is any virus which replicates using Reverse transcription, the formation of DNA from an RNA template

Recent taxonomic proposals by the Herpesviridae Study Group

Herpes viruses are double stranded DNA viruses assigned to Group I. The Herpesviridae Study Group has proposed that herpes viruses be assigned to a newly defined order, Herpesvirales. They also propose that the currently unassigned family Herpesviridae be reassigned to the new herpes order. In addition, they propose that the families Alloherpesviridae and Malacoherpesviridae also be assigned to the new order. [1]

Group I - dsDNA viruses

Group II - ssDNA viruses
