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.
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.
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.
HIV
A red eye spot in Chlamydomonas is a stigma, which is a light-sensitive organelle that helps the organism orient itself towards light for photosynthesis. The red color comes from pigments within the stigma that aid in light absorption.
white blood cell differential test
The rat has, or recently had, a viral infection.
Infection of the host cell then leading to recombination to the host cell's DNA.
the lion has a cell phone technology that detects the prey.
The white blood cell fights off infection in the immune system.
A strategy for activity-based enzyme detection using a novel enamide-based chemical strategy is described. Enzymatic cleavage of an amide.
Lysogenetic infection
Any disease or infection.
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.
lytic infection
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.
White blood cells will increase to fight off the infection.
