When a virus takes over the machinery of a cell, it forces the cell to manufacture:?

D.\n\nIt produces more viral particles up to the point where the cell cannot hold anymore and bursts. The amount of viral particles released is called the "viral burst size" and depends on the virus species. The released particles infect new cells and continue the cycle. This is why virus growth is an exponential curve.

The cell membrane regulates what comes in and what leaves the cell....it kind of acts like a filter!

Several more viruses are created. All of the virus components are assembled together. they go through tail maturation, head maturation and they basicly assemble together to create more virus particles.

Viral populations do not grow through cell division, because they are acellular; instead, they use the machinery and metabolism of a host cell to produce multiple copies of themselves. They may have a lytic or a lysogenic cycle, with some viruses capable of carrying out both. A virus can still cause degenerative effects within a cell without causing its death; collectively these are termed cytopathic effects. Released virions can be passed between hosts through either direct contact, often via body fluids, or through a vector. In aqueous environments, viruses float free in the water.\n\nIn the lytic cycle, characteristic of virulent phages such as the T4 phage, host cells will be induced by the virus to begin manufacturing the proteins necessary for virus reproduction. As well as proteins, the virus must also direct the replication of new genomes, the technique used for this varies greatly between virus species but depends heavily on the genome type. The final viral product is assembled spontaneously, though it may be aided by molecular chaperones. After the genome has been replicated and the new capsid assembled, the virus causes the cell to be broken open (lysed) to release the virus particles. Some viruses do not lyse the cell but instead exit the cell via the cell membrane in a process known as exocytosis, taking a small portion of the membrane with them as a viral envelope. As soon as the cell is destroyed the viruses have to find a new host.

It's complex.  Basically the virus infects cells, and the viral protein is present on the cell surface by MHC molecules.  The circulating T cells then can latch on to and identify the virus-infected cell as foreign.  That specific T-cell then proliferates, and starts hunting down infected cells.  There is alot more going on, including antibody production and release by B cells.\n\nWell described in this book chapter.

There's also cell apoptosis.  infected cells put out a self-destruct signal so the virus can't reproduce.  its actually what i work on, with herpes

Viruses can't replicate on their own so you have to do it in a cell culture.  Look up "cell culture" and you will find lots of information as this has been done for quite a few years now.

When a cell becomes 'worn out', the body replicates the cell so that the cells function can continue uninterrupted.  \n\nCancer occurs when a cell tries to replicate itself and makes a mistake when transcribing the genetic encoding to the new cell.  The resulting new cell is mutated, and is no longer able to accomplish the function the cell is designed for.  \n\nThe next time it replicates, the mutation is duplicated, and frequently exacerbated, during the duplication process.  \n\nEach time this occurs, the resulting product of the attempt to replicate becomes more and more mutated, and less and less able to accomplish the function of the cell.\n\nThe cells then begin to clump - since the cell is attempting to carry out its assigned function and finds itself unable to do so.  This triggers the mechanism which causes the cell to replicate; so that the resulting product of replication will be able to carry out the cells primary function.  \n\nWhen the replication is incapable of accomplishing the primary function of the cell, it triggers another replication.  The clump grows larger and larger, and eventually you have a tumor.

You can get infected with a different strain of the virus.  The HIV virus mutants.

Viruses need to be inside of a  host cell (human, bacteria, plant etc.) to reproduce. So to get inside the host they have surface proteins (sticking out of a lipid bilayer-just like most mammalian cells) that are able to trick the host cell into letting it inside, that's where it does the damage to the host. ---To simplify the virus needs to have a Protein Coating that is similar to the Protein Receptors on its host cell in order to infect it.---

C. \n\nIf a strain is resistant to one drug, and it survives to proliferate in the presence of only that drug, a larger population of the virus with that resistance will be produced to infect other cells and pass on the resistance. However, If that single-resistant virus has to contend with a different drug's mechanism, it has no defense that will allow it to proliferate. In the case of being infected with two or more strains of the same virus, a spectrum of drugs (cocktail) is used to defend against multiple resistance mechanisms. With each additional drug in the cocktail, the likelyhood of the virus mutating such that it can defeat all of those defense mechanisms decreases.

A virus is a submicroscopic parasitic particle that infects cells in biological organisms. The study of viruses is virology.\n\nViruses are obligate intracellular parasites that lack the cellular machinery for self-reproduction. Viruses infect eukaryotes and prokaryotes such as bacteria; viruses infecting prokaryotes are also known as bacteriophages or phages. Typically viruses carry a small amount of genetic material, either in the form of DNA or RNA, but not both, surrounded by some form of protective coat consisting of proteins, lipids, glycoproteins or a combination. The viral genome codes for the proteins that constitute this protective coat, as well as for those proteins required for viral reproduction that are not provided by the host cell.\n\nViruses are non-living particles that can only replicate when an organism reproduces the viral RNA or DNA. Viruses are considered non-living by the majority of virologists because they do not meet all the criteria of the generally accepted definition of life. Among other factors, viruses do not move or metabolize on their own. However, a comprehensive definition of life is still somewhat elusive since some bacteria (considered living) like rickettsia exhibit both characteristics of living and non-living particles.

A whole cell is just that...a whole, not-cut-up, not-pieces-of-other-cells, functioning cell.\n\nThey didn't just take out the cytoplasm.  They didn't just take out mitochondira.  They took the whole cells.

I cant really write a story!\nThe cell membrane and lysozymes guard the cell from the things which cause harm.  The DNA in the nucleus determines what type of cell it is could be equivelent to religion or rules in society.  RNA transcribe from DNA and make 1000's of proreins which do 10000's of different thing in the cell.  This is a bit like a production line in a factory.  The proteins are made in steps using different types of RNA.  The proteins go through postage and packaging in the endoplasmic reticulum.  This is a bit like a post office because they get marked for postage for different regions in the cell.  The mitochondria would have to be the powerstations!\nThe cell cytoskeletion is like the motorway and roads.  \n\nThe DNA could also be thought of as a library and the RNA thought of as the students.\n\nCant think of anything else!
