How does a virus divide its self?
A virus cannot divide by itself because it is not a living organism. Instead, it hijacks a host cell's machinery to replicate its genetic material and produce new virus particles. The virus then assembles these new particles and releases them to infect other cells.
What is an example of a microbe that causes cell death?
Viruses are a good example. They infect the body cells, make them produce replicates of themselves (new virus particles) and then the cells they have invaded are killed as the new virus particles burst open the cell to release the new particles to infect more cells. Until your body's immune system can create antibodies to inactivate the virus particles, this Lytic cycle of viral reproduction continues in each cell that is invaded. See the related question below about the Lytic cycle for more detail.
What is a host cell for a virus?
A host cell for a virus is a cell that the virus can infect and hijack to replicate itself. The virus enters the host cell, takes over its machinery to produce more virus particles, and then spreads to infect other cells.
Where does viral reproduction occurs?
Viral reproduction occurs inside host cells. Viruses infect host cells and use their cellular machinery to replicate and produce new virus particles. This process eventually leads to the release of new viruses, which can go on to infect other cells and continue the cycle of infection.
How does a hidden virus multiply?
A hidden virus multiplies by hijacking the host cell's machinery to replicate its genetic material and produce new viral particles. The virus then releases these new particles, which can go on to infect other cells and continue the replication cycle.
What is lytic reproduction?
ex. a virus enters a cell, replicates, and then "lyses" (ruptures) the cell. those virus particles are now free to infect other cells.
Why cant every virus infect every living cell?
Viruses can only infect specific cells that have the necessary receptors on their surface for the virus to attach to. Each virus is adapted to infect specific types of cells based on these interactions. This specificity limits the range of cells that a virus can successfully infect.
How does the structure of a virus help it survive?
The structure of a virus, with its protein coat and genetic material, allows it to enter host cells, replicate its genetic material, and produce new virus particles. This structure also helps protect the virus from the host's immune system and other environmental factors. Additionally, the compact size and shape of viruses enable them to efficiently infect host cells and spread from one organism to another.
What do viruses do with their DNA?
Viruses use their DNA or RNA to replicate themselves within a host cell. They hijack the cell's machinery to make copies of their genetic material and produce new virus particles, which can then infect other cells. This leads to the spread of the virus within the host and potentially to other individuals.
The human immunodeficiency virus may infect what cells?
sperm cells
What are the viral genes for?
Viral genes encode proteins and enzymes that are necessary for the virus to infect host cells, replicate its genetic material, and produce new virus particles. These genes also help the virus evade the host immune response and manipulate host cell functions to favor virus replication.
How does an active virus multiply?
Once inside a cell, a virus's genetic material takes over of the cell's functions. It instructs the cell to produce the virus's proteins and genetic material. These proteins and genetic material then assemble into new viruses.
