What are the 6 DNA viruses?

| Human herpes virus 6 (HHV6) | Herpesviridae | ds |
| Human herpes virus 8 (HHV8) | Herpesviridae | ds |
| Human papillomavirus | Papovaviridae | ds |
Are DNA and RNA viruses?
The genetic material of a virus can be either DNA or RNA. The viruses that contain DNA as their genetic material are called the DNA viruses. RNA viruses, on the other hand, contain RNA as their genetic material. DNA viruses are mostly double-stranded while RNA viruses are single-stranded.
How do you classify virus?
Viruses are classified on the basis of morphology, chemical composition, and mode of replication.
Is Covid a RNA virus?
COVID-19, short for “coronavirus disease 2019,” is caused by the novel coronavirus SARS-CoV-2. Like many other viruses, SARS-CoV-2 is an RNA virus. This means that, unlike in humans and other mammals, the genetic material for SARS-CoV-2 is encoded in ribonucleic acid (RNA).
What is an RNA virus vs DNA virus?
DNA and RNA viruses are two types of viruses with different types of genetic material. DNA viruses contain DNA in the genome while RNA viruses contain RNA. The replication of DNA viruses occurs inside the host’s nucleus while it occurs in the host’s cytoplasm in RNA viruses.
Is Covid 19 RNA or DNA virus?
What are the 4 types of viral genomes?
Viral genomes exhibit extraordinary diversity with respect to nucleic acid type, size, complexity, and the information transfer pathways they follow. Thus, viral nucleic acids can be DNA or RNA, double-stranded or single-stranded, monopartite or multipartite, linear or circular, as short as 2 kb or up to 2500 kb long.
What are the 4 classifications of viruses?
I: dsDNA viruses (e.g. Adenoviruses, Herpesviruses, Poxviruses) II: ssDNA viruses (+ strand or “sense”) DNA (e.g. Parvoviruses) III: dsRNA viruses (e.g. Reoviruses) IV:(+)ssRNA viruses (+ strand or sense) RNA (e.g. Coronaviruses, Picornaviruses, Togaviruses)
Do all viruses contain both DNA and RNA?
Viruses contain either DNA or RNA, they NEVER contain both. Now whether viruses containing DNA makes them superior to there only-RNA containing counterparts..that is debatable.
What is the shape of all RNA viruses?
All (─) RNA viruses are Helical shaped except Reovirus. Bun yavirus, Para myx ovirus, Rhab dovirus, Ortho myxovirus, Fi lovirus, Delta virus, Arena virus. Bun nies Myx ed with Rhab ies Are Tho ught (Ortho) to Fi ght in the Delta Arena. All (+) RNA viruses are Icosahedral shaped except Corona virus.
What is the structure of simple viruses?
The simple viruses are either icosahedral or helical. Icosahedral viruses can either be simply a naked caspid virus or it can be an enveloped caspid virus. Think of our DNA! We have a helical structure..
What is the lysogenic cycle of a virus?
Lysogenic cycle: Incorporation of the viral DNA into the host DNA, no lysis of the cell. 19) Example of a single-stranded DNA virus. 20) Example of double-stranded RNA virus. Re ovirus @Mnemonics: RE ad RNA double time.
