Question

A virus is referred to as a particle rather than a cell because structurally it is a A) RNA core in a carbohydrate envelope. B) nucleus surrounded by a protein coat. C) plasmid of DNA surrounded by a capsid. D) RNA or DNA core surrounded by a protein coat.

Answer 1

Answer: The answer is D/RNA or DNA core surrounded by a protein coat.

Explanation: One reason a virus is considered to be a particle rather than a cell is because structurally it is only a RNA or DNA core surrounded by a protein coat. It has none of the other features of bacterial cells.

Answer 2

The correct option is D.

A virus refers to an infectious micro organism that is made up of nucleic acid molecule that is enclosed within a protein coat. Viruses are only able to reproduce and multiply when they come in contact with living cells, in the absence of living cells they remain dormant and they do not show any sign of been a living thing. The nuclei acid molecule of a virus can be in form of a DNA molecule or a RNA molecule.
