Doss [256]

Answer:

A. Viruses do not contain RNA or DNA.

Explanation:

This is not a reason why viruses violate the conditions for life. Viruses do contain DNA or RNA, as they are usually made up of a central core of either DNA or RNA surrounded by a coating of protein. However, there are several other characteristics of life that viruses do not fulfill. Viruses are not made up of cells. They have no energy metabolism and do not grow or produce waste. They also do not respond to stimuli and do not reproduce independently.
