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: -Capsid-Nucleic acid is enclosed in a shell of proteins called a capsid. Proteins are arranged in subunits known as capsomeres and then tightly integrated within nucleic acid giving it a shape of polygon-like sphere or a helix.

Detailed explanation-3: -What happens to the virus protein coat when a bacterial cell is infected? It remains on the outside of the host cell. T4 life cycle to facilitate the replication of viral genome?

Detailed explanation-4: -Ribosomes are tiny particles found in the cellular structure which is absent in viruses. They are sites for protein synthesis in the cell. Bacteria are prokaryotic organisms that do not contain cell organelles that are membrane-bound. Instead, they have ribosomes in their cell.
