Viruses

Question

Viruses
A) consist of multiple cells.
B) are smaller than cells.
C) contain a nucleus.
D) contain ribosomes.
E) consist of only a single cell.

Accepted Answer

Viruses are much smaller and simpler than cells, as they consist of only genetic material (DNA or RNA) enclosed in a protein coat. They do not have a nucleus or other organelles, and are not considered living organisms as they cannot replicate on their own and require a host cell to reproduce.
