- Answer 3: Viruses are not considered alive because they lack many of the properties that scientists associate with living organisms. Primarily, they lack the ability to reproduce without the aid of a host cell, and don't use the typical cell-division approach to replication.nswer 3: Viruses are not considered alive because they lack many of the properties that scientists associate with living organisms.

Viruses: Viral Structure, Replication and Function In addition, in order to spread the viruses also need to withstand the immune system. A special category of viruses is those that cause disease only when the immune system is deﬁcient in some way; these are called opportunists, and opportunistic infection is one of the main problems in patients with, for example, AIDS.irus spread control. Viral diseases can be prevented from spreading by vaccinations and the most successful of these is the small pox vaccine that has completely eradicated the disease in 1980. It is hoped that several other viruses, such as polio and measles, will follow.

- Split and merge into it. Answer by D4est. Confidence votes 40.6K. Actually viruses don't reproduce, but replicate. It's sort of a cloning process. They use either the process of the Lytic Cycle for replication or they use replication without lysis with a process known as Budding.es, but viruses need another product to reproduce. The viruses injects it DNA into living cell and viral DNA then directs the cell to make material for the viruses covering … . The viral DNA make more viral DNA.

Viruses: Viral Structure, Replication and Function Many viruses cause no harm or disease whatsoever. However, some viruses may attack certain cells and multiply within them. Once mature the daughter viruses break the cell and spread elsewhere. This is called a lytic infection.Eventually, if host immunity operates effectively, the virus-infected cell may be killed by the host, leading to interruption of the virus cycle and cure of the infection. special category of viruses is those that cause disease only when the immune system is deﬁcient in some way; these are called opportunists, and opportunistic infection is one of the main problems in patients with, for example, AIDS.

Viruses: Dead or Alive Viruses are considered non-living because they do not contain any components of a living cell and do not have a cell membrane. They also have to have living host in order to reproduce.Without a living host, they are basically organic chemicals that do nothing. They do not react to stimuli.iruses are considered non-living because they do not contain any components of a living cell and do not have a cell membrane.

Are viruses alive? Viruses are not alive. They do not have all of the 10 traits of life, therefore making them non living. They have living space, reproduce, respond to surroundings but that's about it. Having a Virus trial in class right now. On the side that says that they are not alive, so that it what I am supporting right now.hey are alive. I think they are alive because how can something not living cause so much damage to something living, example, us. That also have this system in themselves where they create alternatives to the things they lack. 1.

- Dormant viruses can lie within a human host until the proper conditions for their activity are provided. You might think of viruses' as robots that need to take over a factory to make more of themselves. Without that, the viruses are dormant.930: the first time a virus is seen by the human eye --- thanks to the introduction of the electron microscope. Dead or Alive: viruses are not classifiably alive or dead. They seem to be in limbo between each state.

Virus-like particle Virus-like particles resemble viruses, but are non-infectious because they contain no viral genetic material. The expression of viral structural proteins, such as Envelope or Capsid, can result in the self-assembly of virus like particles. VLPs derived from the Hepatitis B virus and composed of the small HBV derived surface antigen were described in 1968 from patient sera. VLPs have been produced from components of a wide variety of virus families including Parvoviridae, Retroviridae, Flavivirid

Viruses and the tree of life 2. Viruses are polyphyletic. In a phylogenetic tree, the characteristics of members of taxa are inherited from previous ancestors. Viruses cannot be included in the tree of life because they do not share characteristics with cells, and no single gene is shared by all viruses or viral lineages.While cellular life has a single, common origin, viruses are polyphyletic – they have many evolutionary origins..

Is virus a multicellular or an unicellular organism? Virus is considered as a living organism since it doesn't have what we call a well-defined cell. It has a protein coat and genetic material only. It is a matter of controversy whether to classify viruses as living or non-living. They lack all other cell components.

- Determining which nationally notifiable infectious diseases are reportable in NNDSS reporting jurisdictions was determined by analyzing results of the 2010 CSTE State Reportable Conditions Assessment (SRCA).uring 2010, West Nile virus (WNV) disease cases were reported from 40 states and the District of Columbia. The number of reported WNV neuroinvasive disease cases increased 62% from that reported in 2009, and the reported incidence of neuroinvasive disease was 0.20 cases per 100,000 population.

- Some scientists speculate that viruses started as rogue segments of genetic code that adapted to a parasitic existence. All viruses contain nucleic acid, either DNA or RNA (but not both), and a protein coat, which encases the nucleic acid. Some viruses are also enclosed by an envelope of fat and protein molecules.In its infective form, outside the cell, a virus particle is called a virion. Each virion contains at least one unique protein synthesized by specific genes in its nucleic acid.ther viruslike particles called prions are composed primarily of a protein tightly integrated with a small nucleic acid molecule. Viruses are generally classified by the organisms they infect, animals, plants, or bacteria.

Viruses, Prions, And Viroids Viruses are and infective agent that have nucleic acid molecules in a protein coat. They are widely considered nonliving but also have traits of being living by the particular state that they are in. They cannot survive with out a host cell and depend on protein syntheses of living cells to reproduce.here are many forms of viruses and they can do remarkably terrible things. The most common form of a virus is the Influenza virus, or even more commonly known; the flu. It can be spread as all viruses through the air, by being swallowed, or inhaled, and also through skin to skin touch.

RNA virus Purified RNA of a negative-sense virus is not infectious by itself as it needs to be transcribed into positive-sense RNA; each virion can be transcribed to several positive-sense RNAs.

Virus latency From Wikipedia, the free encyclopedia. Virus latency (or viral latency) is the ability of a pathogenic virus to lie dormant (latent) within a cell, denoted as the lysogenic part of the viral life cycle.A latent viral infection is a type of persistent viral infection which is distinguished from a chronic viral infection.Latency is the phase in certain viruses' life cycles in which, after initial infection, proliferation of virus particles ceases. However, the viral genome is not fully eradicated.atency is the phase in certain viruses' life cycles in which, after initial infection, proliferation of virus particles ceases. However, the viral genome is not fully eradicated.
