Question

Virus differs from bacterium in having

• A. Cell wall
• B. Cytosol
• C. DNA as genetic material
• D. DNA or RNA with no ribosomes

Answer 1

The correct option is D DNA or RNA with no ribosomes

A virus is made up of a core of genetic material which is either DNA or RNA surrounded by a protective coat called a capsid which is made up of protein. The nucleic acid may be single or double-stranded. Ribosomes are absent in viruses. Bacteria are prokaryotes which contain circular double-stranded DNA as genetic material. Bacteria do not contain RNA as genetic material and ribosomes are present in a bacterial cell.

So, the correct answer is 'DNA or RNA with no ribosomes'.
