DNA virus

From WikiMD's Medical Encyclopedia

(Redirected from SsDNA virus)

DNA virus is a type of virus that uses DNA as its genetic material and replicates using a DNA-dependent DNA polymerase. The group is divided into families depending on their genome (double-stranded DNA, single-stranded DNA, etc.) and the method of replication.

Overview[edit]

DNA viruses belong to either Group I or Group II of the Baltimore classification system for viruses. They include both double-stranded (ds) DNA viruses (e.g., Herpesviridae) and single-stranded (ss) DNA viruses (e.g., Parvoviridae).

Replication[edit]

The replication cycle of DNA viruses is complex and involves several stages. These include attachment, penetration, uncoating, replication, assembly, and release.

Attachment and Penetration[edit]

The virus attaches to the host cell using specific receptors on the surface. Following attachment, the virus penetrates the cell membrane and enters the cell.

Uncoating[edit]

Once inside the cell, the viral capsid is removed (uncoating), exposing the viral DNA to the cellular environment.

Replication[edit]

The viral DNA then enters the nucleus where it is replicated by the host's DNA polymerase.

Assembly and Release[edit]

Newly synthesized viral proteins are assembled into virions in the cytoplasm. The virions are then released from the cell, either by causing the cell to burst (lysis) or by budding off from the cell membrane.

Families of DNA Viruses[edit]

There are several families of DNA viruses that infect humans. These include:

Each of these families includes multiple species that cause various diseases in humans.

Diseases Caused by DNA Viruses[edit]

DNA viruses are responsible for a wide range of diseases in humans. These include:
