What is the virus in resident evil called?
In the original Resident Evil and Resident Evil Zero, the central virus is the T-virus or "Tyrant virus." In Resident Evil 2, Resident Evil 3: Nemesis,both installments of Resident Evil: Survivor, and both installments of Resident Evil: Outbreak, it's the G-virus or "Gene virus." In Resident Evil: Code Veronica the virus is the T-Veronica or "Tyrant-Veronica" virus and in Resident Evil: Dead Aim it's the T/G Virus.
What is the outer covering of a virus called?
A capsid. Some viruses have an additional layer called the envelope, which is derived from the cell membrane of the host cell. http://en.wikipedia.org/wiki/Virus#Structure
What is the virus called which causes influenza?
What is the virus called which causes influenza?Influenza virus. But there are many of them so they’re named H1N2 and so on. They change all the time. So, if the vaccine for the current flu epidemic was not made for the appropriate virus it fails (obviously!).Your question reminds me of the famous question: “What river flows under the Bridge on the Thames?”
Why is virus called so?
A virus is a Micro organism thatcan spread itself through carriers.is lifeless until it enters the host.can dictate a host (living cell), by injecting a copy of its own DNA.can’t replicate by itself , but does so through the cell division of living cells already infected by it.disrupts the self defence mechanism of the host.starts showing symptoms over time and creates problems for us. Sometime leads to death.When we talk about Computer viruses on the other hand are malicious scripts that simulate the activities of the microbe virus at software level. Analogy can be driven as follows.A computer virus is a small script thatspreads through removable storage devices or spam mails.is lifeless (as dead as a normal file) until it gets attached to a process of the host computer.keeps on injecting its script to unaffected files , making them affected.cannot replicate by itself unless it gets itself attached to some live processes, which has the ability to fork.disrupts the self defence mechanism of the system (OS).starts showing symptoms over time like hiding files/folders, blocking task manager etc making the system slow. Sometime leads to formatting OS.There may be other analogies too. But these are some of the basic traits that a virus normally shows. Antivirus may be one of the antibiotics but awareness and prevention are always the best option for such malwares..
Why is the cell invaded by a virus called a 'host' cell?
Viruses are intracellular parasites. That means they need a host cell in order to survive and replicate. Once they invade the host cell, they use its resources and organelles in order to replicate. Think of it as "hosting" a party or an overnight houseguest. While they're in your home, they use your water, eat your food, sleep on your couch, etc. It's the same general idea in regards to host cells. Hope that makes sense :)
Why is a computer virus called a 'virus' and not 'bacteria' or something else?
Virus, in biological terms is defined as A virus is a small infectious agent that replicates only inside the living cells of other organisms.A virus has no life outside it's host. It essentially is bare bone genetic material which has no way of sustaining/replicating on it's own. A virus uses the facilities of it's host to replicate and sustain itself. In addition to this a biological virus can alter the DNA of host organism (which by the way is being used for genetic engineering).Similarly, a computer virus which is simply a few lines of codes has no life outside a host machine.From wiki [Timeline of computer viruses and worms]Computer Virus was coined by Frederick Cohen for describing self-replicating computer programs. In 1984 Cohen uses the phrase "computer virus" – as suggested by his teacher Leonard Adleman – to describe the operation of such programs in terms of "infection". He defines a 'virus' as "a program that can 'infect' other programs by modifying them to include a possibly evolved copy of itself."
Why is a virus called an obligatory parasite?
Because it cannot function or replicate without a host. Virus particles outside the cell are inert, and perform no metabolic processes or environmental interaction. Therefore, it is obligated to enter a cell in order to replicate and perform functions of ‘life’.
What is the virus called that is nicknamed "Red Death"?
Smallpox.
Why are viruses called biological puzzles?
Foremost, viruses are neither living nor non-living. They are simply inanimate, complex organic matter and can’t even multiply on their own. Yet, they manage to infect and hijack the host cell machinery so as to make copies of the virus.Many viruses have this knack of evading the immune system by constantly changing their genetic material. So whatever Antigenic peptide was presented (if any) by and to the cells of immune system for generating a response against these viruses, cannot be used for carrying out an immune response with substantial intensity, because the genetic sequences of the virus has changed. (It is like when you have to go to the airport to catch a criminal you have never met. But you are given a recent photograph of them so that you identify them. No big deal, right ? But then, they are too clever and just had a major reconstructive plastic surgery so that their face is nothing like in the photograph you’ve been given. And they pass by you, uncaught, right under your nose.)This poses a constant challenge in the way of drug/vaccine development against many diseases caused by viruses, be it flu or HIV.I reckon this suffices for viruses to be called as “ Biological puzzles”.
What is a virus made up of?
A virus is a tiny bundle of genetic material - either DNA or RNA - carried in a shell called a viral coat, or capsid, which is made up of protein. Some viruses have an additional layer around this coat called an envelope. When a virus particle enters a cell and begins to reproduce itself, this is called a viral infection. The virus is usually very, very small compared to the size of a living cell. The information carried in the virus's DNA allows it to take over the operation of the cell, converting it to a factory to make more copies of itself. For example, the polio virus can make over one million copies of itself inside a single, infected human intestinal cell.
