Explanation
The most accurate statement about viruses is that they contain genetic material (either DNA or RNA) enclosed in a protein coat, and they lack a prokaryotic or eukaryotic nucleus. Viruses are nucleoprotein entities that can utilize the synthetic machinery of a living cell of the host organism for their multiplication, which does not involve growth and division. They have either RNA or DNA as genetic material and a protein coat.
