Located in central region
Two major functions
Contains only 1 nucleus
Fungi may have several nuclei

3. Parts of the Nucleus Nuclear envelope: 2 pospholipid bilayer membranes
Nuclear pores: shallow depressions
Nucleolus: produces ribosomes by protein synthesis
Chromosomes: in forms of DNA
Chromatin: proteins in a complex structure

4. Krabbe Disease Rare and Inherited Presence of globoid cells
Impairs the growth or development of the myelin sheath
