Detailed explanation-1: -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. Next, the viral particles are assembled into new viruses.
Detailed explanation-2: -Viral DNA that becomes embedded in a bacterial host cell’s DNA is called a prophage. Viral DNA that becomes embedded in an eukaryotic cell’s DNA is called a provirus. The prophage/provirus may remain part of the DNA of the host cell for many generations.
Detailed explanation-3: -Each virus consists of a nucleocapsid (protein coat) that surrounds a core of RNA (ribonucleic acid) genetic material. Surrounding the nucleocapsid is a lipid envelope that contains the glycoprotein spikes haemagglutinin (H) and neuraminidase (N).
Detailed explanation-4: -Viruses cannot replicate on their own, but rather depend on their host cell’s protein synthesis pathways to reproduce. This typically occurs by the virus inserting its genetic material in host cells, co-opting the proteins to create viral replicates, until the cell bursts from the high volume of new viral particles.
