What is a virus called that invades bacteria?
A virus that infects bacteria is called a bacteriophage. Bacteriophages are specific to infecting bacterial cells and can inject their genetic material into the host bacterium, leading to replication and eventual destruction of the bacterial cell.
How did Hershey and Chase separate the virus from bacterial host?

What is the use of the tail of a virus?
The tail of a virus, particularly in bacteriophages (viruses that infect bacteria), plays a crucial role in the infection process. It functions as a mechanism for attachment to the host cell, allowing the virus to inject its genetic material into the bacterial cell. The tail can also aid in the recognition of specific receptors on the bacterial surface, ensuring that the virus targets the appropriate host. Overall, the tail is essential for the successful entry of the virus into its host.
What is it called when a virus hides for a while as part of bacterial chromosome?
This process is known as lysogeny, where a virus integrates its genetic material into the chromosome of its host bacterium and remains dormant until conditions are favorable for reactivation.
A virus that infects bacteria?
A virus that infects bacteria is called a bacteriophage. Bacteriophages inject their genetic material into the bacteria and use the host's machinery to replicate. They are being studied for potential use in treating bacterial infections in humans.
What is the difference between a bacterial lysogenic life cycle and a lyric life cycle?
In a bacterial lysogenic life cycle, the virus integrates its DNA into the host's genome and replicates along with the host cell. In a lytic life cycle, the virus infects the host cell, replicates rapidly, and then bursts the cell to release new viral particles.
The cell or organism which a virus depends is called?
This is the host (organism) and the cell is called the host cell.
The cell a virus lives on or in is called?
A virus will replicate within a host cell.
What is a virus called outside a host cell?
A virus outside a host cell is generally referred to as a virion. This is the inactive form of the virus that is unable to replicate until it enters a suitable host cell.
How does a virus multiplied?
A virus injects its DNA into the host cell making it produce multiple copies of that DNA and multiple copies of the protein capsule of that virus. After a while, the host cell becomes full of many copies of that virus, then the host cell explodes releasing all the new viruses. If the host cell is a bacterium and the the virus is a bacterophage, this phenomenon is done in two ways either by the lytic cycle in which virus DNA survives and the bacterial cell is destroyed,or the lysogenic cycle in which virus DNA is incorporated in the host cell DNA.
What are the four steps an active virus takes to reproduce itself in a bacterial cell?
Attachment: The virus attaches to the surface of the bacterial cell. Entry: The virus injects its genetic material into the bacterial cell. Replication: The viral genetic material replicates using the host's cellular machinery. Release: The newly formed virus particles are released from the bacterial cell to infect other cells.
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.
