2. they are acellular, don't contain cytoplasm or organelles

3. they can mutate

4. they possess Either RNA or DNA or sometimes both

5. they are non living structures

structure of virus

they have either RNA or DNa as their genetic material. the nucleic acid may be single or double standard. its components are nucliec acid, protein coat, capsid

Answer 2

Answer: Viruses are infectious agents with both living and nonliving characteristics.

Living characteristics of viruses include the ability to reproduce – but only in living host cells – and the ability to mutate.

Nonliving characteristics include the fact that they are not cells, have no cytoplasm or cellular organelles, and carry out no metabolism on their own and therefore must replicate using the host cell's metabolic machinery.

Most viruses have either RNA or DNA as their genetic material. The nucleic acid may be single- or double-stranded.This is structure of virus.
