Which one of the following steps occurs during the multiplication of animal viruses but not during the multiplication of bacteriophages?
One key step that occurs during the multiplication of animal viruses but not bacteriophages is the process of uncoating. In animal viruses, after the virus enters the host cell, the viral capsid is removed to release the viral genome into the host's cytoplasm. In contrast, bacteriophages typically inject their genetic material directly into the bacterial cell, leaving the capsid outside and bypassing the need for uncoating.

What event occurs in bacteriophage multiplication in animal virus replication?
In bacteriophage multiplication, the event that occurs that is not found in animal virus replication is the injection of viral DNA directly into the host cell, where the phage attaches to the bacterial surface and transfers its genetic material without entering the cell. In contrast, animal viruses typically enter host cells through receptor-mediated endocytosis or membrane fusion, leading to the release of their genetic material into the host's cytoplasm. This fundamental difference highlights the distinct mechanisms of viral entry and replication between bacteriophages and animal viruses.
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.
List and describe the structural components of viruses?
Infectious particles consisting of nucleic acid encased in a protein coat and, in some cases, a membranous envelope. The smallest viruses are only 20 nm in diameter. The genome of viruses may consist of double-stranded DNA, single-stranded DNA, double-stranded RNA, or single-stranded RNA, depending on the kind of virus. Lack the enzymes for metabolism and the ribosomes for protein synthesis. Identify host cell (needed for reproduction) by a lock and key type system of outer proteins.
Why are cell walls not needed for animal cells?
every cell has a cell wall. It is needed for vital protection from viruses.
Does a virus excrete?
The viruses inject the waste material into the host cells, The host cells remove the waste product by exocytosis by engulfing the waste material in a vesicle and transporting it outside the cell.
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.
What event occurs in bacteriophage multiplication in animal virus replication?
In bacteriophage multiplication, the event that occurs that is not found in animal virus replication is the injection of viral DNA directly into the host cell, where the phage attaches to the bacterial surface and transfers its genetic material without entering the cell. In contrast, animal viruses typically enter host cells through receptor-mediated endocytosis or membrane fusion, leading to the release of their genetic material into the host's cytoplasm. This fundamental difference highlights the distinct mechanisms of viral entry and replication between bacteriophages and animal viruses.
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.
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

Why most viruses that infect bacteria have tails whereas most viruses that infect animals and plants do not?
Bacterial viruses, or bacteriophages, often have tails to help them attach to specific receptors on the bacterial cell surface. Animal and plant viruses typically do not need tails because they enter host cells through different mechanisms, such as membrane fusion or endocytosis. The diversity of host organisms and cell types likely contributes to the variety of viral structures seen across different types of viruses.
Do viruses have a place in the animal kingdom?
No, because viruses aren't alive.

Is nucleic acid found in viruses?
Yes, nucleic acid is found in viruses. Viruses can contain either DNA or RNA as their genetic material, which carries the instructions for viral replication within host cells. The nucleic acid in viruses is packaged within a protein coat called a capsid.
