Discovery of Nucleus The nucleus was discovered in 1833 by Robert Brown due to the improvements in microscope technology. Robert Brown discovered the nucleus in the epidermal cells in an orchid In 1911 Ernest Rutherford came to the conclusion that every atom had a positively charged nucleus Robert Brown

Location of the Nucleus The nucleus takes up a larger proportion of the cell while located near the rough endoplasmic in animal and plant cells. Averages about 5 μm in diameter.

Structure of the Nucleus Nuclear envelope: The membrane in eukaryotes that encloses the nucleus, separating it from the cytoplasm. It surrounds the nucleus and is composed of two layers. Contains numerous openings for nuclear traffic Nucleolus: located in the nucleus, formed from various chromosomes and active in the synthesis of ribosome's Nucleus: An atom’s central core, containing protons and neutrons and the chromosome- containing organelle of a eukaryotic cell. Nuclear pore: passages in which larger molecules can pass through

Function of Nucleus The nucleus directs protein synthesis by synthesizing messenger RNA according to instructions provided by the DNA. Regulates all cell activity by controlling the enzymes present. The chromatin is composed of DNA in the nucleus. The DNA contains the information to produce proteins. Adenine, thymine, cytocine, and guanine. Depending on the organization of these bases depicts the structure of the amino acids Three processes that enable the cell to manufacture protein: - Replication allows the nucleus to make exact copies of its DNA - Transcription allows the cell to make RNA working copies of its DNA - Translation the Messenger RNA is used to line up amino acids into a protein molecule Messenger RNA is transported into the cytoplasm via the nuclear pores.
