A
A membrane-enclosed nucleus.

D
Ribosomes.
Verified step by step guidance1
Understand the structure of bacterial cells: Bacteria are prokaryotic organisms, meaning they do not have membrane-bound organelles like eukaryotic cells.
Identify the location of DNA in bacterial cells: Unlike eukaryotes, bacteria do not have a nucleus. Instead, their DNA is located in a region called the nucleoid.
Clarify the concept of the nucleoid: The nucleoid is an irregularly-shaped region within the cell where the bacterial chromosome is located. It is not enclosed by a membrane.
Differentiate between prokaryotic and eukaryotic cells: Eukaryotic cells have a membrane-enclosed nucleus where DNA is stored, while prokaryotic cells, like bacteria, have their DNA in the nucleoid.
Review the options given: A membrane-enclosed nucleus and mitochondria are features of eukaryotic cells, not bacteria. Ribosomes are present in bacteria but are not where DNA is found. The correct answer is the nucleoid.
