Understand the difference between prokaryotic and eukaryotic cells. Prokaryotic cells do not have a nucleus, while eukaryotic cells do.
Recognize that in eukaryotic cells, DNA is enclosed within a nuclear membrane, forming a distinct nucleus.
Identify that prokaryotic cells, such as bacteria, have DNA that is not enclosed in a nuclear membrane. Instead, their DNA is located in a region called the nucleoid.
Recall that animal cells, plant cells, and eukaryotic cells all fall under the category of eukaryotes, meaning they have a nucleus with a nuclear membrane.
Conclude that the cell type with DNA not bound in a nuclear membrane is the prokaryotic cell.
