Here is the marking for the characteristics of prokaryotes and viruses:
| Characteristics | Prokaryotes | Viruses | |-----------------------------------|-------------|---------| | can reproduce on their own | ✔️ | | | contain DNA or RNA | ✔️ | ✔️ | | Has a cell membrane | ✔️ | | | Has a protein coat | | ✔️ |
Explanation:
- Can reproduce on their own: Prokaryotes can reproduce independently through processes like binary fission. Viruses cannot reproduce on their own; they need a host cell to replicate.
- Contain DNA or RNA: Both prokaryotes and viruses can contain either DNA or RNA. Prokaryotic DNA is typically circular and found in the cytoplasm, while viruses can be composed of various forms of DNA or RNA.
- Has a cell membrane: Prokaryotes have a cell membrane as part of their cellular structure. Viruses do not have a cellular structure and therefore do not have a cell membrane.
- Has a protein coat: Viruses have a protein coat (capsid) that protects their genetic material. Prokaryotes do not have a protein coat; instead, they have a cell wall and membrane.
