Question

The virus that infects bacteria is called _________
A. Cyanophage
B. Mycophage
C. Bacteriophage
D. None of these

Answer 1

Hint: The virus that infects bacteria is contagious to a cell and its new parts are replicated and released through the cell membrane. This kind of cycle is used for genetic material as the virus injects its own DNA or RNA into the bacterial cell of the host.

Complete answer: Viruses are non-cellular species and a small infectious agent with an inert crystalline structure that characterizes them. Pasteur provided the name of the virus. In the year 1892, D.J. Ivanowsky. Either DNA or RNA is present as genetic material in viruses. Typically, phages are classified as bacteriophage viruses. In the sense that a virus often behaves as a problem outside of a living cell, viruses are distinct from normal species. A virus injects the genetic material into the cell upon finding a living cell and the genetic material becomes incorporated with the host cell's genome. As the host cell replicates, it often multiplies the viral genome. Viruses are typically infectious, but some healthy viruses are known as bacteriophages. These infect bacteria that are otherwise likely to damage us.
Let us look at all the options to get the correct answer,
-Cyanophages, also known as Cyanophyta, or blue-green algae, are viruses that infect cyanobacteria.
-Mycophage is a fungi-infecting virus.
-Bacteriophage is the virus that attacks bacteria (for example: \[T\text{ }II\text{ }phage,\text{ }M13,~\phi ~174,\]). It catches and replicates bacteria by using a variety of copies of its machinery.
Hence, the correct answer is C-Bacteriophage.

Note: Viruses that infect the plant have single-stranded RNA and there is single or double-stranded RNA or double-stranded DNA for the viruses that infect the animal. The bacterial infecting viruses, i.e. bacteriophages, are double-stranded DNA.
