Are viruses single or double-stranded DNA?
Are viruses single or double-stranded DNA?
DNA Viruses (Classes I and II) Class I viruses contain a single molecule of double-stranded DNA (dsDNA). In the case of the most common type of class I animal virus, viral DNA enters the cell nucleus, where cellular enzymes transcribe the DNA and process the resulting RNA into viral mRNA.
What are some examples of DNA viruses?
1.47. 2.1 Virus With DNA
| Virus family | Examples (common names) | Nucleic acid type |
|---|---|---|
| Hepadnaviridae | Hepatitis B virus | ds-RT |
| Herpesviridae | Herpes simplex virus, varicella-zoster virus, cytomegalovirus, Epstein–Barr virus, varicella virus | ds |
| Papillomaviridae | Human papillomavirus, bovine papillomavirus | ds circular |
Which virus is DNA virus?
DNA virus: A virus in which the genetic material is DNA rather than RNA. The DNA may be either double- or single-stranded. Major groups of double-stranded DNA viruses (class I viruses) include the adenoviruses, the herpes viruses, and the poxviruses.
Is rotavirus double-stranded DNA?
The rotavirus genome consists of 11 segments of double-stranded (ds) RNA and is contained in the viral core along with the minor structural proteins, VP1 and VP3 (10).
What are double stranded RNA viruses?
Double-stranded ( ds) RNA viruses are a diverse group of viruses that vary widely in host range ( animals, plants, fungi, and bacteria ), genome segment number (one to twelve) and virion organization ( T-number, capsid layers or turrets). Members of this group include the rotaviruses,…
What are the types of RNA viruses?
RNA vi·rus. a group of viruses in which the core consists of RNA; a major group of animal viruses that includes the families Picornaviridae, Reoviridae, Togaviridae , Flaviviridae , Bunyaviridae, Arenaviridae, Paramyxoviridae, Retroviridae, Coronaviridae, Orthomyxoviridae, and Rhabdoviridae.
What is double strand RNA?
Double stranded ribonucleic acid ( RNA) is a unique form of RNA that appears with two complementary strands, instead of a single strand in isolation, as is more common for this genetic material. RNA contains the code for a number of biological activities and plays an important role in living organisms.
