How do all viruses differ from bacteria?Group of answer choicesViruses do not have any nucleic acid.Viruses are obligate intracellular parasites.Viruses are filterable.Viruses do not reproduce.Viruses are not composed of cells.
Solution
Viruses differ from bacteria in several ways:
-
Viruses are obligate intracellular parasites: This means that viruses can only reproduce by infecting a host cell. They rely on the host cell's machinery to replicate. Bacteria, on the other hand, are independent organisms that can reproduce on their own.
-
Viruses are filterable: This refers to the fact that viruses are much smaller than bacteria. They can pass through filters that trap bacteria, which is how they were originally discovered.
-
Viruses do not have any nucleic acid: This is incorrect. Viruses do contain nucleic acids (either DNA or RNA) which carry their genetic information. Bacteria also contain nucleic acids, but they have both DNA and RNA.
-
Viruses do not reproduce: This is partially true. Viruses cannot reproduce on their own like bacteria can. They must infect a host cell and use the host's cellular machinery to make more viruses.
-
Viruses are not composed of cells: This is true. A virus is a small infectious agent that can only replicate inside the cells of another organism. Bacteria, on the other hand, are single-celled organisms.
