The Nucleus
Presentation by: Alejandro Perez and Abigail Ragasa

2. Functions Stores DNA (tightly packed)
Manages the cell's activities (growth, protein synthesis, cell division)
Plays a role in DNA replication
Regulates passage of molecules from the cytoplasm (Nuclear Envelope)

3. Where? The Nucleus is specific to eukaryotic cells.
Not all eukaryotic cells have a nucleus.
Some eukaryotic cells have more than one nucleus.
No Prokaryotic cells have nuclei.

4. Structure Nuclear envelope Nuclear pore(s) Chromatin Chromosomes
Nucleolus
Nucleoplasm

5. Nucleus Interaction Replicates DNA
mRNA: messenger code created by nucleus in order to interact with other organelles
Ribosomes: mRNA is deciphered; AA are converted to proteins

6. Nucleus Interaction
Endoplasmic reticulum: responsible for protein synthesis (RNA)
Golgi bodies: modifies proteins
Lysosomes: contains digestive enzymes to break down proteins and other particles
