Viruses have some, but not all, of the characteristics of living things.
One of the characteristics is they contain genetic material (DNA), which is a characteristic that all living things must have in order to be considered living. And also when inside a host, they are able to reproduce, which all living things must be able to do.
No, not all living things have cells. While all living things are made up of cells, some organisms like viruses are considered living but do not have cells. Instead, viruses are composed of genetic material (DNA or RNA) enclosed in a protein coat.
Mutations happen in ALL living things (and also in viruses)!!!!!!
Yes **G1N4** I thought some living things are not organisms, because they are not free living.

"All living things are made of cells" would be a biological observation, and it's only true if we disqualify viruses.
Presence of nucleic acid.

viruses are not considered to be living organisms as they lack the cellular structure and cannot carry out cellular functions on their own. They can only replicate by hijacking the machinery of living cells. Therefore, viruses do not challenge the concept that all living things are made of cells.

Yes, all living things do (as well as viruses, although they force other living things to make them instead of doing it themselves).
No, not all living things contain cells. Viruses, for example, are considered living but are not made up of cells. They are instead composed of genetic material encased in a protein coat.
