NUCLEUS
NATURAL BORN LEADER
• ”Brain” of the cell and leads the cell in its functions
• Responsible for major cellular activities of an eukaryotic cell
• Houses the DNA
• Largest and most prominent organelle in the cell
THE DNA
• Contains chromosomes, which are made of DNA,
• DNA allows cells to synthesize proteins
• Without DNA stored in the nucleus, the eukaryotic cell would not be able to produce
proteins, therefore would not be able to carry out its major life functions
NUCLEAR MEMBRANE
• Protected by a double membrane, the nuclear membrane
• Has pores allowing the movement allowing movement of substances through it
• Joins with the endoplasmic reticulum
NUCLEOLUS
VICE PRESIDENT
• “Brain” of the nucleus
• Largest organelle in the nucleus
• Ribosome factory
FUNCTIONS
• Ribosome production factory
• Regulates transactions of proteins and cellular functions in the cell
• Assembles and produces ribosomes that are needed for protein production
STRUCTURE
• Main structural components
– Dense fibrilla component (DFC)
– Fibrilla centers (FC)
– Granular components (GC)
MUDSLINGING
MITOCHONDRIA
• Over 44 different mitochondrial diseases
• Most are caused by autosomal defects
MUDSLINGING
ENDOPLASMIC RETICULUM
• Malfunction causes:
– Diabetes
– Parkinson's disease
– Alzheimer’s disease
– Bipolar disorder
MUDSLINGING
RIBOSOMES
• Malfunction can lead to:
– Cancer
– Skeletal abnormalities
– Mental retardation
– Cardiac defects
