How do you describe the reproduction of polio in the body?
Polio virus can infect only human being. Like other viruses, polio virus infect the cells. After getting attached to the cell, the virus genome is inserted into the cell body. The genetic material of the host is broken into small fragments and assembled as per the genome of the polio virus. Multiple such copies are formed and then released in the body to infect the new cells.
How does a virus attatch to a host cell?
A virus attaches to a host cell by recognizing and binding to specific proteins or receptors on the cell surface. This attachment is necessary for the virus to enter the host cell and begin the process of infection.
How does the west nile virus attack the host cell?
The West Nile virus enters host cells by binding to specific cell surface receptors that allow it to gain entry. Once inside the cell, it replicates its genetic material and produces viral proteins, disrupting normal cellular functions. This can lead to cell death and the release of new virus particles to infect neighboring cells.
What property of a virus determines its attachment to a host cell membrane?
The specific viral proteins on the surface of the virus determine its attachment to host cell membrane receptors. These proteins bind to complementary host cell receptors, allowing the virus to attach and enter the host cell.
What is viral specificity?
Viruses are highly specific and can only attack particular cells of a particular organism. Ex. Polio virus attacks nerve cells Mumps virus attacks salivary glands Hepatitis virus attacks liver cells
The cell infected by a virus is referred to as the?
The cell infected by a virus is referred to as the host cell. The virus hijacks the host cell's machinery to replicate and produce more virus particles.
Does the virion attach to the surface of the host cell in the mumps virus?
Yes, the mumps virus attaches to the surface of the host cell through specific interactions between its hemagglutinin-neuraminidase (HN) protein and sialic acid receptors on the host cell membrane. This attachment is a crucial first step for the virus to enter the host cell and initiate infection. Once attached, the virus can then fuse with the host cell membrane, allowing it to release its genetic material into the host cell.
What is the cell in which a virus reproduces?
This is called a host cell. In the beginning, a virus will attach itself to the host cell and release its genetic material into it. This genetic material interferes with the host cell's enzymes which cause them to form parts in which will create a new virus.
What is the cell that a virus infects?
Host Cell
How do you describe an active virus?
The virus attaches to the host cell, it takes over the functions of the host cell, and it eventually destroys it. If there was no host cell, the virus would die.
What is the specific host cell of the West Nile Virus?
The specific host cell for West Nile Virus is the neuronal cell in the central nervous system. Once inside these cells, the virus can replicate and cause damage, leading to neurological symptoms in infected individuals.
What does the protein structure of a virus have to do with the attachment to host cells?
The protein structure of a virus typically includes specific proteins on its outer surface that help it attach to receptors on host cells. This attachment is crucial for the virus to gain entry into the host cell, infect it, and replicate. The binding specificity between viral proteins and host cell receptors is a key determinant of the virus's ability to infect specific cell types.
