How is the entrance of bacteriophages into their host cell different than the entrance of animal viruses into their host cell?

Bacteriophages enter a host cell by attaching to specific receptors on the surface of bacteria, including lipopolysaccharides, techoic acids, proteins, and flagella.
For for a virus to infect a host cell, the cell must have receptors on its surface for the virus to attach to. The receptors are normal molecules involved in routine cellular function, but a portion of the surface of the virus resembles the chemical shape of the body's molecule that would normally bind to the receptor, allowing the binding of the virus to cell to happen.

The event that occurs in bacteriophage multiplication that does not occur in animal virus replication is?
The event that occurs in bacteriophage multiplication that does not occur in animal virus replication is the injection of only the viral nucleic acid into the host cell. Viruses that infect bacteria are specifically called bacteriophages.
Is nucleic acid found in viruses?
Yes nucleic acid forund in viruses it can either be DNA e.g. bacteriophages which have single stranded DNA as S13, PHI 174. The another nucleic acid can be RNA e.g. TMV
How do viruses infect eukaryotic cells?
In bacterial viruses, the protein coat remains outside the cell and only the viral genome is injected into the cell. In animal viruses, the virus attaches to specific receptors on the plasma membrane and the whole virus is taken in by endocytosis (pinocytosis or phagocytosis). The viral envelope (if present) is stripped off inside the cell, and the separation of the viral genome from the protein coat then takes place. Not all infections of animal host cells result in lysis of the cell (as in the lytic cycle of bacteriophages). In the case of enveloped animal viruses, the viruses are released by a budding process. The process is slow and the host cell may remain alive and continue to release viruses over a long period of time. In some cases the virus may become dormant (though remaining infectious) inside the host cell, appearing spontaneously at a later time. (Unlike temperate bacteriophages that integrate their DNA into the genome of the host cell as provirus, animal viruses do not usually integrate into the animal genome during the latent stage.) Finally, some animal viruses may cause transformation of host cells to the cancerous state.--Differences between bacteriophages and viruses that infect eukaryotic cells
Of what material is the envelope present in some animal viruses composed?
The envelope present in some animal viruses is composed of lipids. This lipid material is derived from the cell membrane of the host.
Which is the largest a plant cell an animal cell or a bacterial cell?
animal cell ____________________________________ viruses are not cells. but it would be the animal cell.
What is the part of the cell that viruses invade?
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.

The event that occurs in bacteriophage multiplication that does not occur in animal virus replication is the injection of only the viral nucleic acid into the host cell. Viruses that infect bacteria are specifically called bacteriophages.
What is the pathogen attacks specific cells and injects genetic materials?
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
Is nucleic acid found in viruses?
Yes nucleic acid forund in viruses it can either be DNA e.g. bacteriophages which have single stranded DNA as S13, PHI 174. The another nucleic acid can be RNA e.g. TMV
What viruses are stable and why?
stable viruses are very symtom, for example influenza. and viruses that are not stable, they are like animal viruses...

Do viruses have a place in the animal kingdom?
No, because viruses aren't alive.

What is the simpilist animal form?
bacteria or viruses
Does Animal Jam really spread viruses?
No
Does animal jam give viruses?
yeah they give
How are animal and non animal virus different?
Animal viruses don't affect all animals. One example is how rabies from bats isn't seen in all species of animals around (eg.) vampire bat feeding sites. Also, human viruses don't only affect humans. An example of this is how swine flu can be passed from pigs to humans and back again. Viruses all pretty much work the same, with virus DNA being inserted into a host cell, then replicating, and causing different effects depending on the type of virus and type of cells targeted.
