1) DNA replication is carried out in the endoplasmic reticulum.

2) Eukaryote cells are characterized by having only one nucleus.

3) The nucleus is composed of nucleoplasm and a nuclear envelope.

4) The nuclear envelope separates the nucleoplasm from the cytoplasm.

5) The nuclear envelope is composed of one membrane where nuclear pore complexes are inserted.

6) Protein synthesis happens in the nuclear envelope.

7) The molecular composition of the outer and inner membranes is similar.

8) The basal lamina maintains the integrity of the nuclear envelope.

9) Gene expression of eukaryote cells couldn't be regulated without the nuclear envelope.

10) DNA is also known as chromatin.

11) The chromatin is found in the cytoplasm.

12) Euchromatin is a type of loosely condensed chromatin.

13) Facultative heterochromatin is a type of chromatin that does not decondensate during interphase.

14) The nucleolus cannot be observed with a light microscope but can with an electron microscope.

15) The nucleolus is involved in the synthesis of ribosomes.

16) The fibrillar center is the region of the nucleolus where most RNA is transcribed and processed.

17) There are many copies of the gene that codes for RNA.
