Draw a well-labelled diagram of a eukaryotic nucleus. How is it different from nucleoid?
Diagram of a eukaryotic nucleus
Major differences between eukaryotic and prokaryotic nuclei:
1. The eukaryotic nucleus is membrane bound but the prokaryotic nucleus is membrane-less.
2. Prokaryotic cells do not contain DNA in the form of chromosomes.
3. Prokaryotic cells do not possess nucleolus as there is no membrane-separated nucleolus and cytoplasm.
Nucleus | Nucleoid |
1. Larger in size | 1. Smaller in size |
2. Bounded by double membrane | 2. Not bounded by any membrane |
3. It contains nucleolus | 3. Does not contain nucleolus |
4. It contains DNA associated with histone proteins | 4. It contains naked DNA i.e., DNA is not associated with histone proteins |
5. Present in eukaryotic cells. | 5. Present in prokaryotic cells. |
