Detailed explanation-1: -The essential components of infectious viral particles are nucleic acid (the genome) and protein. In addition, all enveloped viruses contain lipid in the envelope and carbohydrate in their glycoprotein peplomers (as well as that in the nucleic acid).

Detailed explanation-2: -Viruses are microscopic particles that exist almost everywhere on Earth. They are present in animals, plants, and other living organisms, and they can sometimes cause diseases. Viruses are biological entities that can only thrive and multiply in a host, which is a living organism such as a human, an animal, or a plant.

Detailed explanation-3: -All viruses contain nucleic acid, either DNA or RNA (but not both), and a protein coat, which encases the nucleic acid. Some viruses are also enclosed by an envelope of fat and protein molecules. In its infective form, outside the cell, a virus particle is called a virion.

Detailed explanation-4: -A virus is made up of a core of genetic material, either DNA or RNA, surrounded by a protective coat called a capsid which is made up of protein. Sometimes the capsid is surrounded by an additional spikey coat called the envelope. Viruses are capable of latching onto host cells and getting inside them.

Detailed explanation-5: -COVID-19. Influenza (the flu) HIV, which can lead to AIDS. Meningitis (there is also bacterial meningitis) Pneumonia (there is also bacterial pneumonia) Human papillomavirus (HPV) Herpes. Rotavirus. More items
