What are DNA virus examples?
Examples of DNA viruses are herpes, smallpox, hepatitis B, adenoviruses, and warts. The Baltimore classification system for viral classification divides viruses into seven groups. dsDNA viruses reside in groups I and VII, and ssDNA viruses are in group II.
Which of the following is not Rnaviruse?
Answer is (c) Adenoviruses Adenoviruses are DNA viruses. Avian leukemia virus, bacteriophage MS-2 and influenza virus are RNA viruses.
Is rabies virus a retrovirus?
These viruses are enveloped and have a single stranded RNA genome with negative-sense. The genetic information is packaged as a ribonucleoprotein complex in which RNA is tightly bound by the viral nucleoprotein….Rabies virus.

Is chickenpox a DNA or RNA virus?
Varicella-Zoster Virus (VZV) VZV is a DNA virus and is a member of the herpesvirus group. Like other herpesviruses, VZV persists in the body as a latent infection after the primary (first) infection; VZV persists in sensory nerve ganglia. Primary infection with VZV results in varicella.
Is virion a viral protein?
virion, an entire virus particle, consisting of an outer protein shell called a capsid and an inner core of nucleic acid (either ribonucleic or deoxyribonucleic acid—RNA or DNA). The core confers infectivity, and the capsid provides specificity to the virus.
Is polio a ssRNA virus?
Poliovirus is composed of an RNA genome and a protein capsid. The genome is a single-stranded positive-sense RNA (+ssRNA) genome that is about 7500 nucleotides long.
Which is an example of RNA virus?
1.1. RNA Viruses. Human diseases causing RNA viruses include Orthomyxoviruses, Hepatitis C Virus (HCV), Ebola disease, SARS, influenza, polio measles and retrovirus including adult Human T-cell lymphotropic virus type 1 (HTLV-1) and human immunodeficiency virus (HIV).
Why is Influenza A retrovirus?
Retroviruses are a type of virus in the viral family called Retroviridae. They use RNA as their genetic material and are named for a special enzyme that’s a vital part of their life cycle — reverse transcriptase.
Is Ebola virus RNA or DNA?
The virion nucleic acid of Ebola virus consists of a single-stranded RNA with a molecular weight of approximately 4.0 x 10(6).
Is shingles RNA or DNA?
Varicella-zoster virus (VZV) is an enveloped double-stranded DNA virus belonging to the family Herpesviridae [70]. VZV is also called human herpesvirus type 3. VZV infects the lungs and enters into the nerves, including the cranial nerve ganglia and dorsal root ganglia.
Do virions contain proteins?
According to older reports, there are approximately 2000 molecules of each Gag protein in a virion, which together represent about three quarters of the protein component of the virus. Although this is a conventionally accepted number, the exact number of copies of Gag in a virion has not been established.
What is the genetic material of rhabdoviruses?
Rhabdoviruses carry their genetic material in the form of negative-sense single-stranded RNA. They typically carry genes for five proteins: large protein (L), glycoprotein (G), nucleoprotein (N), phosphoprotein (P), and matrix protein (M).
What are the characteristics of rhabdoviruses?
The individual virus particles (virions) of rhabdoviruses are composed of RNA, protein, carbohydrate and lipid. They have complex bacilliform or bullet-shaped. All these viruses have structural similarities and have been classified as a single family. The virions are about 75 nm wide and 180 nm long.
What is the genome size of Rhabdoviridae?
The family Rhabdoviridae has a non-segmented single stranded negative-sense RNA and its genome ranges in size from approximately 11 kb to almost 16 kb. It is one of the most ecologically diverse families of RNA viruses with members infecting a wide range of organisms.
Where does rhabdovirus replicate in the body?
Replication of many rhabdoviruses occurs in the cytoplasm, although several of the plant infecting viruses replicate in the nucleus. The rhabdovirus matrix (M) protein is very small (∼20–25 kDa) however plays a number of important roles during the replication cycle of the virus.
