Question
- A virus is made up of _______.(a) Protein coat and nucleic acid(b) Protein coat and mitochondria(c) Nucleic acid and cell membrane(d) Nucleic acid, cell wall and cell membraneSol: (a) Protein coat and nucleic aci
Solution
The correct answer is (a) Protein coat and nucleic acid. A virus is a small infectious agent that can only replicate inside the living cells of an organism. Viruses are made up of two or three parts: genes, made from either DNA or RNA, long molecules that carry genetic information; a protein coat that protects these genes; and in some cases an envelope of lipids that surrounds the protein coat when they are outside a cell.
