viruses are specific to the cells they infect called host cells
Viruses have to attach them selves by way of a protein called a recognition factor. They bind to receptors on the host cell and then lose their capsid (coat).
Viruses can infect animals, plants and bacteria, and the attachments vary. In animal viruses: Animal cells have a cell membrane. Viruses attach to certain proteins in that membrane. In plant viruses: Plants can also be infected with viruses. Since they have cell walls, viruses attach to those when infecting plants. In bacteriophages (viruses that infect bacteria): Special viruses called bacteriophages attach to the cell walls of bacteria by way of proteins.
Viruses can attach themselves to host cells, bacteria, fungi, and other viruses for the purpose of infecting and replicating within these organisms. They require a specific receptor on the surface of the target cell to bind and gain entry for their replication process.
Cancer viruses, like all viruses, require specific mechanisms to infect host cells, typically involving the binding of viral proteins to cell receptors. The presence or absence of tails in viruses generally refers to structural characteristics and does not directly determine their ability to infect cells. Many viruses without tails, such as certain types of retroviruses, can still effectively attach to and enter host cells. Therefore, viruses can infect cells regardless of their structural features, as long as they possess the necessary components for attachment and entry.

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.

Viruses survive inside the human body by hijacking host cells to replicate and propagate. They attach to specific receptors on cell surfaces, enter the cells, and use the host's cellular machinery to produce new viral particles. Additionally, many viruses can evade the immune system through various mechanisms, such as mutating their surface proteins or hiding within cells, allowing them to persist and spread within the host.
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.
Viruses attach specific cells and inject genetic material. There are viruses called bacteriophages that infect bacteria be injecting their genetic material into the bacterial host and invading their protein machinery. With animal viruses that infect animal cells (much larger than bacteria), the virus either injects genetic material OR gets into the cell whole before it begins to unleash its pathogenic effects
Yes.It infects fungi,plants,animals and bacterias
Capsids are protein coats that protect the genetic material of a virus. They help viruses to attach to and enter host cells, as well as shield the viral genome from environmental damage. Capsids also assist in the release of the viral genetic material into host cells during infection.
