Detailed explanation-1: -Viruses cannot reproduce by themselves, they must have a living host cell in order to multiply. Viruses are not made of cells and, therefore, cannot perform the same functions as living organisms. They act as parasites, entering a living host cell in order to replicate and spread.
Detailed explanation-2: -The virus’s genome is uncoated from the protein and injected into the host cell. Then the viral genome hijacks the host cell’s machinery, forcing it to replicate the viral genome and produce viral proteins to make new capsids.
Detailed explanation-3: -SARS-CoV-2, the virus that causes COVID-19, has a protein capsid that is surrounded by a phospholipid envelope. Inside its capsid is a genome of RNA. Spike proteins called, S proteins, recognize the ACE2 receptors of host cells allowing the virus to enter the host cell.
