What is the 3 parts in a virus?

User Avatar

Asked by Wiki User

Viruses generally consist of a protein coat called a capsid, genetic material such as DNA or RNA, and sometimes an outer lipid envelope. The capsid protects the viral genetic material, allowing the virus to infect host cells and replicate.

Is the FBI a bacteria virus or a parasite?

The FBI is not a bacteria, virus, or parasite. The FBI (Federal Bureau of Investigation) is a law enforcement agency of the United States government that investigates and enforces federal laws to protect and defend the country against criminal threats.

Why virus is denied as kingdom?

User Avatar

Asked by Wiki User

Viruses are not considered a kingdom because they lack the characteristics of living organisms, such as the ability to reproduce independently and carry out metabolic processes. Instead, they are classified as acellular entities that rely on host cells for replication.

What is polymorphic virus?

User Avatar

Asked by Wiki User

A polymorphic virus is a type of malicious software that constantly changes its appearance in order to avoid detection by antivirus programs. It achieves this by encrypting its code with different algorithms each time it infects a new file or system. This makes it difficult for traditional signature-based antivirus software to identify and remove the virus.

What is biological virus?

What is Biological Viruses?The prime directive of all organisms is to reproduce and survive, which is also the case for viruses, which in most cases are considered a nuisance to humans. ?Viruses - An OverviewViruses possess both living and non-living characteristics. The unique characteristic that differentiates viruses from other organisms is the fact that they require other organisms to host themselves in order to survive, hence they are deemed obligate parasites.
Viruses can be spread in the following exemplar ways
· Airborne - Viruses that infect their hosts from the open air
· Blood Borne - Transmission of the virus between organisms when infected blood enters an organisms circulatory system
· Contamination - Caused from the consumption of materials by organisms such as water and food which have viruses within
Therefore viruses have many means of getting transmitted from one organism to another. ?Cell Assimilation by a VirusViruses are tiny micro-organisms, and due to their size and simplicity, they are unable to replicate independently. Therefore, when a virus is situated in a host, it requires the means to reproduce before it dies out without producing more viruses.
This is done by altering the genetic make up of a cell to start coding for materials required to make more viruses. By altering the cell instructions, more viruses can be produced which in turn, can affect more cells and continue their existence as a species.
The following is a step by step guide of how an example bacteriophage (a virus that infects bacteria) takes control of its host cell and reproduces itself.
· The virus approaches the bacteria and attaches itself to the cell membrane
· The tail gives the virus the means to thrust its genetic information into the bacteria
· Nucleotides from the host are 'stolen' in order for the virus to create copies of itself
· The viral DNA alters the genetic coding of the host cell to create protein coats for the newly create viral DNA strands
· The viral DNA enters its DNA coat
· The cell is swollen with many copies of the original virus and bursts, allowing the viruses to attach themselves to other nearby cells
· The process begins all over again with many more viruses attacking the hosts' cells
Without a means of defence, the host that is under attack from the virus would soon die. The next page looks at how organisms defend themselves from these ruthless viruses.

What are spikes on viruses made of?

User Avatar

Asked by Wiki User

Spikes on viruses are made up of proteins that are used to attach the virus to host cells. These proteins play a critical role in allowing the virus to enter and infect host cells by binding to specific receptors on the cell membrane.

What is the name for the action carried out by a virus when it is activated?

User Avatar

Asked by Wiki User

The action carried out by a virus when it is activated is typically referred to as executing or running. This involves the virus code being triggered and performing its intended functions, which could include replicating itself, corrupting files, or stealing data.

What is a basic characteristic of a virus?

User Avatar

Asked by Wiki User

A basic characteristic of a virus is that it cannot survive or reproduce on its own. It requires a host cell to replicate and multiply.

Which is not a considered a method that a virus might use to inject itself into its target?

User Avatar

Asked by Wiki User

A virus would not append to inject itself into a target.

Is the proliferation and growth of any microorganism or virus in any area of the body?

User Avatar

Asked by Wiki User

Proliferation and growth of microorganisms or viruses in the body can lead to infection, causing symptoms such as fever, inflammation, and tissue damage. The immune system responds by mobilizing immune cells to combat the invading pathogens, leading to an inflammatory response. If left unchecked, the infection can spread and potentially lead to more severe complications.

What two things does every virus have?

User Avatar

Asked by Wiki User

Every virus has genetic material (DNA or RNA) and a protein coat (capsid) that protects the genetic material.

What do viruses have to support the idea that they are alive?

User Avatar

Asked by Wiki User

Viruses lack the cellular machinery for metabolism and reproduction on their own, which are key characteristics of living organisms. They can only replicate by hijacking host cells. Therefore, viruses are considered more like particles than living organisms.

Is cytomegalovirus is oncogenic virus?

User Avatar

Asked by Wiki User

Cytomegalovirus (CMV) is not considered an oncogenic virus, as it does not directly cause cancer. However, there have been studies suggesting a potential association between CMV infection and certain types of cancer, such as glioblastoma and some types of lymphoma. The exact relationship between CMV and cancer development is still being researched.

Does a virus have hyphae?

User Avatar

Asked by Wiki User

No, viruses do not have hyphae. Hyphae are branching, thread-like structures that make up the body (mycelium) of fungi. Viruses are a different type of microorganism that are not composed of cells and do not have structures like hyphae.

Why is a virus called a bug?

User Avatar

Asked by Wiki User

A virus is sometimes called a bug as a metaphor to describe a programming error or flaw in the system. Just like a bug in the natural world, a virus can disrupt normal functioning and cause problems. This term has been used in the tech industry for a long time and has become common slang.

What separates viruses from living things?

User Avatar

Asked by Wiki User

Viruses lack the ability to carry out basic functions of living organisms, such as metabolism and reproduction, when they are outside a host cell. They also do not have the machinery to generate energy or produce proteins on their own. Viruses are considered obligate intracellular parasites because they rely on host cells to replicate.

Who invented the the first virus?

What happens to the amount of anibodies when the virus has been destroyed?

User Avatar

Asked by Wiki User

When the virus has been destroyed, the production of antibodies specific to that virus will decrease over time since there is no longer a need to fight the virus. However, the immune system retains a memory of the virus, allowing it to mount a quicker and more effective response if the virus is encountered again in the future.

What family of proteins whose specialty is fighting viruses by slowing or stopping their multiplication is known as?

User Avatar

Asked by Wiki User

The family of proteins known for fighting viruses by inhibiting their multiplication is called interferons. Interferons are produced by the immune system in response to viral infections and play a crucial role in protecting the body from viral pathogens.

What does neuraminidase do for a virus?

User Avatar

Asked by Wiki User

Neuraminidase is an enzyme found on the surface of some viruses, such as the influenza virus. Its main function is to cleave sialic acid residues from host cells, which helps the virus to release from infected cells and spread to other cells in the body. Inhibiting neuraminidase activity can prevent viral replication and spread.
