Presentation Transcript Nucleus The Brain of the CellBy: Bryonna AldubayanDefinition • Function • Significance • Structure and Components • Nuclear Envelope and Pores • Nucleolus • Nucleoplasm • Mitosis/Meiosis • Malfunctions/Disease OutlineIn an atom: The nucleus is the center of an atom which contains the protons and neutrons • In a cell: The nucleus is the structure that contains the cell's genetic material (DNA) and controls the cell's activity in a eukaryotic cell. DefinitionThe nucleus regulates all cell activity, growth and reproduction. It controls the cell through protein synthesis. • Protein Synthesis is the process by which amino acids are arranged linearly into proteins through the involvement of ribosomal RNA, transfer RNA, messenger RNA, and various enzymes FunctionThe nucleus contains DNA which contains coded instructions needed for cell reproduction and also produces proteins that control metabolism and other cell functions. Significance& • The nucleus is a spherical double membrane organelle. Components The nucleus contains: • Nuclear Envelope • Pores • Nucleolus • Nucleoplasm StructureThe nuclear envelope is a double phospholipid bilayer membrane which surrounds the genetic material in eukaryotic cells. • Outer membrane • Inner membrane • The nuclear membrane is dotted with thousands of small holes called nuclear pores that allow material to diffuse in
