Detailed explanation-1: -This causes the cell to make a copy of the virus DNA, making more viruses. Many scientists argue that even though viruses can use other cells to reproduce itself, viruses are still not considered alive under this category. This is because viruses do not have the tools to replicate their genetic material themselves.
Detailed explanation-2: -Viruses are not made out of cells, they can’t keep themselves in a stable state, they don’t grow, and they can’t make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
Detailed explanation-3: -This is because viruses do not have the cellular machinery that is required to multiply, hence they hijack a living cell. Another aspect that makes viruses lie on the border between the living and the non-living is their ability to be crystallized.
Detailed explanation-4: -A virus is an infectious microbe consisting of a segment of nucleic acid (either DNA or RNA) surrounded by a protein coat. A virus cannot replicate alone; instead, it must infect cells and use components of the host cell to make copies of itself.
