Question
- Which of the following statements about viruses is true?a. They are acellular.b. They can regulate the movements of substances into and out of the cell.c. They can reproduce outside of living cells.d. They have subcellular compartments.e. They are readily destroyed by antibiotics.
Solution
The correct answer is a. Viruses are acellular. This means they are not composed of cells. Instead, they are particles that consist of a core of genetic material (either DNA or RNA) surrounded by a protein coat. They cannot regulate the movements of substances into and out of the cell, reproduce outside of living cells, have subcellular compartments, or be readily destroyed by antibiotics. These are characteristics of cellular organisms, not viruses. Viruses need to infect the cells of a living host in order to reproduce.
