Choose one · Correct answer highlighted

Explanation

Viruses consist of a protein coat shielding genetic material. According to the NCERT Class 11 Biology text, a fundamental biological rule regarding viral genomes is that 'no virus contains both RNA and DNA'. A virus is either an RNA virus or a DNA virus. The genetic material is the sole infectious component that hijacks the host's cellular machinery to replicate itself.
