Detailed explanation-1: -A host cell is a cell that harbors foreign molecules, viruses, or microorganisms. It may also be a cell that has been introduced with DNA (or RNA), such as a bacterial cell acting as a host cell for the DNA isolated from a bacteriophage.
Detailed explanation-2: -Viruses are composed of a nucleic acid, RNA or DNA-never both.-All viruses have a protein coat (capside) or shell that surrounds and protects the nucleic acid core.-Some viruses have a lipid envelope or membrane surrounding a nucleocapsid core. The source of the envelope is from the membranes of the host cell.
Detailed explanation-3: -Based on their host, viruses can be classified into three types, namely, animal viruses, plant viruses, and bacteriophages.
