THE NUCLEUS

The History
The nucleus was the first part of the cell to be discovered. It was discovered by Anton Von Leeuvanhoek .

THE MAIN FUNCTIONS

• Store and protect genetic infromation
• Regulates gene expression which regulates cell activity
• The "control center" of the cell
• Contains hereditary information of the stucture and function of an organism
• Contains chromosomes

LESSER KNOWN FACTS

• The nucleolus part of the inside of the nucleus makes ribosomes
• Organizes and regulates larger genomes
• The genes can form specialized muscles like skin

THE CELL STRUCTURE (NUCLEAR ENVOLOPE)

• Nuclear membrane
• Made up of the inner and outer membranes
• The outer membrane is part of the endoplasmic riticulm
• The space between the membranes is the perinuclear space
• Separtes the genetic material from the cytoplasm

THE CELL STRUCTURE (NUCLEIC PORES)

• In the nuclear envelope
• Made up of protiens
• Regulate the passage of molecules through the cytoplasm
• Allows RNA and other materials in the nulceus

PARKINSON'S DISEASE

• Occurs when dopamine producing neutrons malfunction an die
• These protiens dying cause the plasy symptoms and most have defective nulclei
• These cells cause the signaling pathways to be reduced
• This causes high reactive oxygen compounds to damage cells
• Dopamine is a neurtransmitter

Role In Protein Synthesis
The nucleus is where DNA is transcribed into RNA. Then the RNA goes through the cytoplasm to its correct location
