NEET BIOLOGY

Detailed explanation-1: -A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea. Viruses are infectious agents with both living and nonliving characteristics.

Detailed explanation-2: -Viruses are typically described as obligate intracellular parasites, acellular infectious agents that require the presence of a host cell in order to multiply. Viruses that have been found to infect all types of cells – humans, animals, plants, bacteria, yeast, archaea, protozoa…

Detailed explanation-3: -A virus is an infectious agent that can only replicate within a host organism. Viruses can infect a variety of living organisms, including bacteria, plants, and animals. Viruses are so small that a microscope is necessary to visualize them, and they have a very simple structure.

Detailed explanation-4: -Viruses infect all types of organisms, from animals and plants. Viruses are not considered true living things, therefore they are not classified under any of the kingdoms. The only living part is the DNA, but it requires a host cell to carry out all necessary life functions.

Detailed explanation-5: -The multiple infection of cells with several copies of a given virus has been demonstrated in experimental systems, and has been subject to previous mathematical modeling approaches.
