The nucleoid region of a prokaryotic cell

A. contains the cell's DNA

B. separates the RNA from the cytoplasm

C. is surrounded by a nucleoid membrane

D. contains the cell's nucleoid membrane

E. is the site of organelle production

A. contains the cell's DNA

Explanation:

Prokaryotic cells such as the bacterial cells and the cells of archaeans do not have a membrane-bound nucleus. Their genetic material DNA is present in the cytoplasm only. However, their genetic material is concentrated in a specific region inside their cells. This is called a nucleoid. Nucleoid does not have any surrounding membrane. It represents the nuclear area where the DNA of the prokaryotic cells is present.
