Detailed explanation-1: -Virology is the study of viruses and virus-like agents, including, but not limited to, their taxonomy, disease-producing properties, cultivation, and genetics. Virology is often considered a part of microbiology or pathology.

Detailed explanation-2: -Virology is the scientific discipline concerned with the study of the biology of viruses and viral diseases, including the distribution, biochemistry, physiology, molecular biology, ecology, evolution and clinical aspects of viruses.

Detailed explanation-3: -Virology covers all aspects of the virus from evolution, structure, life cycle and function to the diseases that they are responsible for and the host defenses against them.

Detailed explanation-4: -Viruses are small, subcellular agents that are unable to multiply outside a host cell (intracellular, obligate parasitism). The assembled virus (virion) is formed to include only one type of nucleic acid (RNA or DNA) and, in the simplest viruses, a protective protein coat.

Detailed explanation-5: -By studying viruses, we can learn about the biology of host cells and organisms, develop strategies against viral disease and manipulate viruses for our own purposes. Some viruses are only a single self-replicating gene, while others can encode almost a thousand proteins and be the size of a bacterium.
