How do vaccines work to limit the spread of computer and biological viruses?

they inject a milder form of the disease , so your body won't be fully affected but will remember how to kill the real disease and its weakness

Note, though, that computer viruses are not prevented using vaccines.

Does viruses releases harmful toxins?

Viruses themselves do not release toxins. Instead, they replicate and spread by hijacking the host cell's machinery. However, some viruses can cause infected cells to release toxins as part of the immune response, leading to symptoms of illness.

What is the modern version of virus called?

The modern version of a virus is called malware, which is a general term that encompasses different types of malicious software such as viruses, worms, trojans, ransomware, and spyware. Malware is designed to disrupt, damage, or gain unauthorized access to a computer system or network.

Why might a dormant virus be difficult to diagnose?

A dormant virus may be difficult to diagnose because it does not actively replicate or cause symptoms, making it challenging to detect using standard diagnostic tests. Additionally, dormant viruses may not shed enough viral particles for traditional diagnostic methods to detect their presence. Specialized tests or specific triggers may be required to detect dormant viruses accurately.

What is one reason a virus that spends long time in the lysogenic cycle could be more dangerous to humans than a virus that does not?

A virus in the lysogenic cycle can hide within the host's cells for extended periods without causing symptoms, allowing it to evade the immune system and antiviral treatments. When it later switches to the lytic cycle, it can rapidly replicate and cause a sudden and severe infection. This delayed onset of symptoms can make it harder to detect and control the virus in the early stages of infection.

What is the function of the capsomere?

Capsomeres are protein subunits that make up the capsid, which is the protein coat surrounding a virus. They help in the assembly of the capsid structure and protect the genetic material of the virus. Capsomeres also aid in the attachment of the virus to host cells during infection.

What are three things viruses cant do?

Reproduce (they make copies rather than reproducing), create waste, and (need energy? i.e. consuming foods)....

wait, can you specify what virus you're talking about?

What does a virus cell look like?

Viruses are not cells and are not made of cells: they are small entities that reproduce inside of cells.

Viruses have many different shapes and forms. They tend to resemble spirals, spheres, and various types of three-dimensional polygons.
The internal structure of a virus is a strand of RNA surrounded by a protein shell.

How do viruses get into your body?

Viruses can enter the body through various routes such as inhalation, ingestion, or through breaks in the skin. They can be transmitted through respiratory droplets, contaminated food or water, or through direct contact with infected individuals. Once inside the body, viruses invade host cells and replicate, leading to infection.

Is the plural of virus viruses?

Most people use "viruses", but if you wanted to be really proper about it, you could treat it as the original Latin word and use "virii" (pronounced like "vye-rye", both syllables rhyme with "eye").

Steps of a virus when a attacking a cell?

  1. Attachment: The virus attaches to the surface of the host cell.
  2. Entry: The virus enters the cell, either by direct fusion with the host cell membrane or by endocytosis.
  3. Replication: The virus releases its genetic material and hijacks the cellular machinery to replicate itself.
  4. Assembly and Release: New virus particles are assembled and released from the cell to infect other cells.

How do capsomeres help in viruses?

Answer by Techsupport

capsid provides the second major criterion for the classification of viruses. The capsid surrounds the virus and is composed of a finite number of protein subunits known as capsomeres, which usually associate with, or are found close to, the virion nucleic acid.

What is a genus name for streptobacillus?

The genus name for Streptobacillus is Streptobacillus. Streptobacillus is a genus of Gram-negative bacteria that are typically rod-shaped and form chains.

How do you explain how copies of viruses are produced?

Viruses replicate by hijacking host cells and using their machinery to make copies of themselves. Once inside a host cell, the virus releases its genetic material, which then directs the host cell to produce viral proteins and assemble new viral particles. These new virus particles can then infect other cells and continue the replication cycle.

How did the work of lister and koch support pasteur's germ theory of disease?

Lister's work on antiseptic techniques, which reduced infection rates during surgeries, and Koch's identification of specific disease-causing microorganisms provided experimental evidence to support Pasteur's germ theory of disease. These discoveries demonstrated the role of microbes in causing infections and helped validate Pasteur's idea that microorganisms were responsible for the spread of diseases.

Why meristem tissues are virus free?

Meristem tissues are virus free because they have a high rate of cell division and low metabolic activity, making them less susceptible to viral infections. Additionally, meristems often lack open plasmodesmata connections that viruses typically use to spread between plant cells. Lastly, meristem cultures are often treated with antiviral agents or heat therapy to eliminate any existing viruses.

Does Pokemon volcano give viruses?

As with any online game, there is a potential risk of downloading viruses when playing Pokemon volcano if you visit third-party sites or download content from unreliable sources. It is essential to only download the game from official sources and ensure your device has proper antivirus protection to minimize the risk of viruses.

True or false the envelope surrounding a virus aids the virus in entering the cell and the virus DNA is found in that envelope?

True. The envelope of a virus helps it enter the host cell by fusing with the cell membrane. The virus DNA can be found enclosed within this envelope, along with other viral proteins necessary for infection and replication.

Why do scientists think there are so many types of viruses?

Scientists believe there are many types of viruses due to their high mutation rates, ability to adapt to different environments, and diverse host range. This variability allows viruses to infect various organisms and evolve rapidly, leading to the emergence of new virus strains and types.

What came first viruses or cells?

The first virus to exist is impossible to say. Microscopic life was not discovered until the invention of the microscope. Bacteria were discovered first because they are bigger than 400 nm (nanometres) in size. Viruses are far simpler and are usually between 20 and 250nm in size.

The first real work on viruses was done by Heinz Fraenkel-Conat in 1910 with his work on TMV (tobacco mosaic virus). This is one of the simplest viruses there is and the most studied.

Viruses are not considered to be living organisms by some biologists because ALL exist in a parasytic form (none fee living) and all rely on their host for reproduction. Others believe they are living organisms because they have an existence of their own separate to the host and are subject to natural selection. One hypothesis is that they are rouge pieces of DNA.

Viruses are too small to exist in the fossil record although there is evidence of their existence because of their effects on other animals and plants. This record goes back as far into the history of life on Earth as humans can go.

How virus differ from cell in size?

Viruses are generally smaller than cells, typically ranging from 20-400 nanometers in size, whereas cells are typically micrometers in size. Viruses are also simpler in structure compared to cells, lacking their own organelles and machinery for reproduction. Viruses are not considered cells because they are acellular entities that require a host cell to replicate.

Where are virus cells located?

The cells in your body are found absolutely everywhere. Skin cells form your skin, nerve cells form your brain and nervous system and muscle cells form your muscles. Almost everything in your body is made of cells.

Bacteria that don't fulfill Koch's Postulates?

Some bacteria may not fulfill Koch's postulates due to various reasons such as the inability to culture them in a lab setting, the presence of asymptomatic carriers, or the complexity of their interactions with the host's immune system. These bacteria may still be implicated in causing diseases based on epidemiological evidence and other experimental data.

How does a virus differ from a toxin?

A virus is a microorganism that can infect living cells and reproduce within them, leading to illness; whereas a toxin is a harmful substance produced by living organisms, which can cause harm to cells and tissues when ingested or absorbed. Viruses require host cells to replicate, while toxins can be produced by various organisms independently.
