Question
Which statement is true?a. A virion contains DNA and RNA.b. Viruses are acellular.c. Viruses replicate outside of the cell.d. Most viruses are easily visualized with a light microscope.
Step 1
Option a suggests that a virion contains both DNA and RNA. However, this is not true. Viruses can contain either DNA or RNA, but not both at the same time. Therefore, option a is incorrect. Option b states that viruses are acellular. This is true. Viruses do not Show more…
