The differences between nucleoids in bacteria and the nucleus in eukaryotes with respect to cellular membranes.

Explanation of Solution
The bacterial chromosome is folded and compressed to be able to fit inside a cell. This highly-folded chromosome is referred to as a nucleoid. The differences between the nucleoid in bacteria and the nucleus in eukaryotes have been tabulated below:
Bacterial nucleoid | Eukaryotic nucleus |
It does not have a membrane. | It is enclosed within a membrane. |
The DNA (deoxyribonucleic acid) is in contact with the cytoplasmic content. | The DNA is isolated from the contents of the cytoplasm. |
Therefore, it can be concluded that a nucleoid comprises a compressed chromosome and is not enclosed in a membrane while the eukaryotic nucleus has a membrane, which turns it into an organelle.
