It raplicates and multiply very rapidly
"Vector" is an agent that can carry a DNA fragment into a host cell. If it is used for reproducing the DNA fragment, it is called a "cloning vector". If it is used for expressing certain gene in the DNA fragment, it is called an "expression vector".Commonly used vectors include plasmid, Lambda phage, cosmid and yeast artificial chromosome (YAC).
The lysogenic cycle replicates the phage genome without destroying the host. Similar to Lytic reproduction, Lysogenic also begins when the phage inserts its DNA or RNA into the host cell through its surface. Once the nucleic acid is inside the cell, it forms a circle, and becomes a part of the genome of the host cell. It does this through genetic recombination, or crossing over. Once it joins the host’s genome, it is called a prophage. Since it is a part of the host cell’s genome, the phage’s genetic information is copied and distributed to the daughter cells of the host cell, which continues dividing naturally. This allows the prophage to be repeatedly copied and passed on without destroying the host cell it depends on for metabolic and reproduction purposes. In order for actual active phages to be produced, the segment of genome from the original phage exits the genome of the host cell and becomes independent. When this occurs, it begins the lytic cycle, destroying the cell, but producing new and functional phages.
The lytic cycle of bacteriophage infection ends with the lysis of the bacterial host cell. Once the phage has replicated its genetic material and assembled new viral particles, it produces enzymes that break down the bacterial cell wall. This rupture releases the newly formed phages into the environment, allowing them to infect other bacterial cells. Consequently, the lytic cycle results in the destruction of the host cell and the propagation of the phage.
Viruses are unable to replicate on their own and require a host cell to do so. Once inside a host cell, a virus hijacks the cell's machinery to produce more copies of itself.
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.
A phage infects bacterial cells by injecting its genetic material into the host bacterium. Once inside, the phage hijacks the bacterium's cellular machinery to replicate and produce more phage particles, ultimately leading to the bacterium's destruction.

Once the T4 bacteriophage injects its genetic material into the host cell, infection becomes irreversible. This usually occurs as soon as the phage's tail fibers attach and the genome is injected, initiating the takeover of the host cell machinery for viral replication.

A bacteriophage ( virus that infect bacteria) can multiply in a cell by two ways:lytic and lysogenic cycle.In lytic cycle, the phage DNA enters the cell, replicate and assembled within the cell and released outside by rupturing the host. It continues to invade the other bacteria.In case of lysogenic cycle the phage DNA once it enter the host cell gets integrated into the host genome and multiply along with host DNA. It remains latent. Upon proper induction, it undergoes lytic cycle again.The viruses that multiply by integrating into the host genome are widely used in gene therapy.

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.
The virus attempts to take over the host cell's DNA, and if successful, when the host cells divide via mitosis, instead of making copies of a healthy cell, the system produces new copies of the virus infected cell, which leads to an infection.
No, viruses do not grow in the same way that bacteria or fungi do. They need a host cell to replicate and spread. Once inside a host cell, viruses use the cell's machinery to make copies of themselves.
This describes a virus. Viruses are unique microorganisms that cannot reproduce on their own; they require a host cell to replicate. Once inside a host cell, they hijack the cell's machinery to produce new virus particles. This dependence on host cells distinguishes viruses from other types of organisms, such as bacteria, which can reproduce independently.
Viruses must infect a host cell in order to replicate. Once inside the host cell, the virus can hijack the cell's machinery to produce new viral particles. Without a host cell, viruses are unable to replicate.
