Which of the following properties are true of both bacteria and archaea?

• A. Both have linear chromosomes.
• B. Both are capable of photosynthesis.
• C. Both lack a membrane-bound nucleus.
• D. Both have a cell wall composed of peptidoglycan.

Answer: (C)

Verified step by step guidance

1. Begin by understanding the basic characteristics of bacteria and archaea. Both are prokaryotic organisms, meaning they do not have a membrane-bound nucleus.
2. Consider the structure of their genetic material. Both bacteria and archaea typically have circular chromosomes, not linear ones.
3. Evaluate their ability to perform photosynthesis. While some bacteria can photosynthesize, archaea generally do not have this capability.
4. Examine the composition of their cell walls. Bacteria often have cell walls made of peptidoglycan, whereas archaea have cell walls composed of different substances, such as pseudopeptidoglycan.
5. Conclude by identifying the property that is true for both groups: both lack a membrane-bound nucleus, which is a defining feature of prokaryotic cells.
