To review:
The differences between nucleoids in bacteria and the nucleus in eukaryotes with respect to cellular membranes.
Introduction:
All living forms have
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.
