How are the steps in the infection of an animal cell by a virus different from the infection of a bacterial cell by a virus?
Infection of an animal cell by a virus typically involves the virus attaching to specific receptors on the cell surface, entering the cell through endocytosis or direct fusion, replicating using host cell machinery, and then releasing new viruses by budding or cell lysis. In contrast, infection of a bacterial cell by a virus (called a bacteriophage) usually involves the phage injecting its genetic material into the bacterium, hijacking the bacterial machinery to replicate, and then causing lysis of the bacterial cell to release new phages.
What type of T cell can tell if another cell is heathly or infected?
CD8+ cytotoxic T cells are primarily responsible for identifying and eliminating infected or cancerous cells. They recognize infected cells through the presentation of foreign antigens on MHC class I molecules. When a CD8+ T cell detects an abnormality, such as a viral infection, it can initiate a response to kill the compromised cell. Additionally, CD4+ helper T cells can also play a role in orchestrating the immune response by supporting other immune cells.
An infection in which DNA of a virus is embedded into a host cell and replicates with host DNA is called what?
This process is called lysogeny, and the host cell is referred to as a lysogenic cell. The integrated viral DNA is known as a prophage.
How does a virus infect your body?
A virus infects your body by attaching to a host cell and injecting its genetic material into the cell. The virus then takes over the cell's machinery to replicate itself, eventually causing damage to the host cell. This can lead to various symptoms of the infection.
What is it called when infection leads quickly to breaking open of host cell?
HIV
Which blood test provides information about the patient's immune system detects certain types of leukemia and determines the severity of infection?
white blood cell differential test
A researcher detects interferon in a laboratory rat and concludes that?
The rat has, or recently had, a viral infection.
How is the lion adapted to be a predator?
the lion has a cell phone technology that detects the prey.
What is true about lysogenic infection?
Infection of the host cell then leading to recombination to the host cell's DNA.
What detects cell activity in a cell?
A strategy for activity-based enzyme detection using a novel enamide-based chemical strategy is described. Enzymatic cleavage of an amide.
What cell fight off infection?
The white blood cell fights off infection in the immune system.
In what type of infection is the host cell not destroyed?
Lysogenetic infection
What disease or infection can affect a cell?
Any disease or infection.
What is the receptor cell that detects the presence or absence of light and allows to see dim light?
The receptor cell that detects the presence or absence of light and allows us to see dim light is called a rod cell. Rod cells are responsible for low-light vision and are located in the retina of the eye.
What is the type of infection in which the host cell bursts and is destroyed?
lytic infection
What are two ways that viruses cause infections?
The two ways that viruses cause infection are by lytic infection and lysogenic infection. The virus can enter into a cell, make a copy of itself and the cause the cell to burst in a lytic infection. When a virus embeds its DNA into the DNA of a host cell and replicates, it is a lysogenic infection.
Which blood cell increases due to an infection in the body?
White blood cells will increase to fight off the infection.
