Question

Quizplus · Accepted Answer

Viruses are not considered living organisms as they cannot carry out metabolism and reproduce on their own. They consist of a nucleic acid (either DNA or RNA) enclosed by a protein coat called a capsid. They must invade a host cell and hijack its cellular processes in order to replicate and carry out their life cycle.
