Detailed explanation-1: -Viruses. Viruses are assembles of organic molecules that consist of some short strands of RNA or DNA encapsulated within a protein shell. They are often referred to as if they were living organisms, but they don’t meet the criteria listed above for living things.
Detailed explanation-2: -Viruses are considered as something between living and non-living because they do not grow or reproduce by themselves. This makes them non-living. However, when a virus enters a living cell of an organism, it obtains energy from the host cell and starts reproducing.
Detailed explanation-3: -Finally, a virus isn’t considered living because it doesn’t need to consume energy to survive, nor is it able to regulate its own temperature.
Detailed explanation-4: -Virus genomes All viruses have genetic material (a genome) made of nucleic acid. You, like all other cell-based life, use DNA as your genetic material. Viruses, on the other hand, may use either RNA or DNA, both of which are types of nucleic acid.
