Viruses are composed of protein and DNA. The DNA encodes the protein as well as the DNA for the virus. Viruses depend on host cells because they are incapable of reproducing themselves. They enter the host cell and the viral DNA is inserted into the host DNA. The virus then "hijacks" the host cells replication machinery to make more viral protein and viral DNA.
What else can I help you with?
Do viruses make waste?
Viruses do not produce waste because they lack metabolic processes to generate waste products. Viruses are not considered living organisms and depend on host cells to replicate and multiply.
Are viruses general or specific to the cells that they infect?
viruses are specific to the cells they infect called host cells
Why do viruses not contradict the idea that all living things are made of cells because?
A virus is an extremely small cell. You can have big cells and little cells. Viruses aren't considered to be alive because they depend on a host cell for energy and reproduction.
Viruses depend on living things for what?
Viruses depend on living cells because they reproduce inside of them.
Viruses cannot do what?
They can not reproduce without a host as reproductive vector. They have no metabolism and do not preform cellular functions. Viruses are genetic material enclosed in a protein capsid.
Do viruses reproduce inside host cells causing them to burst?
Yes, viruses can reproduce inside host cells by hijacking the host cell's machinery to make copies of themselves. This can cause the host cell to burst, releasing the newly formed viruses to infect other cells.
Why do viruses kill?
Your host cells in your body.
Viruses can reproduce only inside what?
host cells!
Is there a difference with viruses and cells?
Yes there is a difference. Viruses are non-living and cells are living This is because Viruses can't reproduce on their own without a host. They don't have a metabolism like cells. They can't maintain homeostasis. They cannot synthesize proteins (they lack the ribosomes to do so) without a host. Without a host viruses can neither generate nor store ATP (adenosine triphosphate). Viruses cannot live unless they have a host.
Why are viruses hard to cultivate in the laboratory?
Viruses are hard to cultivate in the laboratory because they require living host cells to replicate. This dependency on living cells makes it challenging to maintain viruses outside of a host organism. Additionally, viruses can be very specific about the types of cells they can infect, which further complicates the cultivation process.
What are these molecules called that protect potential host cells?
Antibodies protect potential host cells. They act against bacteria and viruses.
What infectious agent live only by invading cells?
Viruses are infectious agents that can only replicate and survive by invading host cells and hijacking their cellular machinery. Once inside a host cell, viruses use the cell's resources to produce more viral particles, which can then go on to infect other cells. This process ultimately leads to the destruction of the host cell as new viruses are released to infect additional cells.
