Question

Quizplus · Accepted Answer

Viruses are not considered living organisms and are not composed of cells. Instead, they consist only of nucleic acids (either DNA or RNA) enclosed by a protein coat, called a capsid. Viruses cannot carry out metabolism or reproduce on their own; they must invade a host cell and take over its machinery in order to replicate.
