Final answer:
The correct answer is C) DNA is present in both archaea cells and bacteria cells. Both groups are prokaryotic, lacking a membrane-bound nucleus and organelles, but they differ in the composition of their cell walls and plasma membrane lipids.
Step-by-step explanation:
The correct statement concerning archaea cells and bacteria cells is: C) DNA is present in both archaea cells and bacteria cells. Both are types of prokaryotes, meaning they lack a membrane-bound nucleus and other membrane-bound organelles. Instead, they have a single circular chromosome of DNA located in the nucleoid region of the cell. While their cellular structures are often quite similar, including components like a cell wall, cell membrane, nucleoid region, ribosomes, and sometimes additional structures such as capsules, flagella, and pili, there are key differences in the chemical composition of these parts. For instance, bacterial cell walls contain peptidoglycan, whereas archaeal cell walls do not. Additionally, the plasma membrane lipids of bacteria are composed of fatty acids, while the plasma membrane lipids of archaea are made up of phytanyl groups.
