Question

Write three characteristic features of virus? How do viruses cause disease?​

Answer 1

Explanation:

• They are acellular, that is, they contain no cytoplasm or cellular organelles.
• They carry out no metabolism on their own and must replicate using the host cell's metabolic machinery. In other words, viruses don't grow and divide.
• The vast majority of viruses possess either DNA or RNA but not both.
