Varicella Zoster Virus Research Paper
Viral biology is one of the most important areas of biology as it looks at the microbiology of diseases and viruses. Without virology we would not have vaccines to inhibit the growth of disease within human hosts.
Zakkkkkkkk4yuhrViruses are microscopic nonliving repositories of nucleic acid that grow within the presence of living Prokaryotic or eukaryotic cells. Viruses contain infectious agents that consist of core genetic material either deoxyribonucleic acid (DNA) or Ribonucleic acid (RNA). This core genetic material is what replicates within a Prokaryotic or eukaryotic cell host. Viruses can be transmitted through sneezing, coughing, direct contact or sexual viruses will be transmitted through bodily fluids during sexual intercourse.

Chicken pox is caused by the Varicella zoster virus and is an airborne infection that is commonly accompanied but the Varicella rash. The Varicella Zoster virus enters ‘through the respiratory tract and conjunctiva’ (Varicella, Dr Cindy Weinbaum) where replication of the viruses starts to take place within 24 – 48hours of being in contact with a primary host. Varicella (Chicken pox) is seen throughout the world as it is a common virus, which is generally passed through primary and middle …show more content…
The Lipid Envelop is the outside structure of the VZV particle and contains glycoprotein spikes that enable to virus to identify and fuss with its targeted cells, within the host. The VZV particle has a natural cover called Tegument; this substance contains the virus, proteins and enzymes which are used by the virus to replicate the particle.
The VZV particle has one more layer; this layer contains and protects the DNA which the particle carries into the nucleus of infected host cells. This layer is the Nucleocapsid. All viruses have a genetic material called Deoxyribonucleic acid (DNA) or Ribonucleic acid (RNA) this genetic material contains proteins that are necessary for the replication of the virus. The VZV particle has a none complex structure allowing it to bind onto the Heparin Sulphate Proteoglycan (See figure 1.1) of the cell wall and quickly attack the host’s

    The nucleic acid of a virus is protected by a protein coat called the capsid. The structure of the capsid is ultimately determined by the viral nucleic acid and accounts for most of the mass of a virus, especially of small ones. Each capsid is composed of protein subunits called capsomeres. In some viruses, the proteins composing the capsomeres are of a single type; in other viruses, several types of protein may be present. In some viruses, the capsid is covered by an envelope, which…

    Viruses – A viruses is a small capsule that holds DNA or RNA, viruses, unlike bacteria are not self-sufficient and need a ‘host’ in order to reproduce, for example: ‘Human Body’. When a virus enters the body, it enters some certain cells and takes over making them the new ‘host cell’ which makes the parts the virus needs to reproduce, the cells are eventually destroyed through this process. The most common virus is the ‘common cold’ which has no cure.…

    First, since we know the viral RNA sequence and its targeting protein, we can investigate it in bioinformatics database, and can acquire some clues or hints about the target proteins. From the bioinformatics database, we might be able to find its structure, similarity with other proteins, functions, and binding domains. In other words, we can get some partial or complete amino sequences of the targeting proteins or information about likeness.…

    Most viruses have either RNA or DNA as their genetic material. The nucleic acid may be single- or double-stranded. The entire infectious virus particle, which is called a virion, consists of the nucleic acid and an outer shell of protein. The simplest viruses contain only enough RNA or DNA to encode four proteins. The most…

    (Talaro) The Varicella-zoster virus is a DNA virus in the same group as the herpes virus. (Varicella) Latency is the main virulence property of Varicella. Human are the sole reservoir of the chickenpox and is spread through human-to-human contact. Chickenpox can be spread through the respiratory tract and conjunctiva. Respiratory transmission occurs through person-to-person when respiratory tract secretions are transferred from an infected individual to a healthy individual. Another form of transmission of Varicella is through respiratory contact of airborne droplets or inhaling aerosols.…

    Herpes Zoster is caused by varicella zoster virus, which is the same virus that causes chicken pox. When a person gets chicken pox and recovers from it, the virus does not go away, it remains in the body, but becomes dormant (inactive). Later in life, the virus can reactivate itself causing herpes zoster. Herpes zoster itself cannot be spread from person to person, but the varicella zoster virus can be spread from one person with active shingles to another person who has never had chicken pox. That…

    Viruses have the biological organization of atoms and molecules because they are made up of nucleic acid and protein. Viruses lack the emergent property of living things, which is the cell. They are not classified in any kingdom of organisms. Viruses compensate by attaching themselves to a host cell and dissolving the cell membrane and then they enter the nucleus of the host cell and force the nucleus to replicate the virus. Viruses lack the ability to metabolize and convert carbohydrates to usable energy. Viruses compensate by using the energy from the host cell. Viruses lack a sense of responsiveness because it happens at a cellular level, which they do not have. Viruses lack DNA because all of them do not have it. They compensate for this by using what they do have. Some viruses have a single strand RNA that is unraveled and replicated by the host cell and some viruses have a single strand DNA that is also replicated by the host cell. They lack the ability to reproduce and develop without the assistance of a host cell. Viruses are constantly changing and mutating for their struggle to…
