  2. Nucleolus - Wikipedia

    en.wikipedia.org/wiki/Nucleolus

    The nucleolus (/ nj uː ˈ k l iː ə l ə s, ˌ nj uː k l i ˈ oʊ l ə s /; pl.: nucleoli /-l aɪ /) is the largest structure in the nucleus of eukaryotic cells. [1] It is best known as the site of ribosome biogenesis. The nucleolus also participates in the formation of signal recognition particles and plays a role in the cell's response to ...

  3. Cell nucleus - Wikipedia

    en.wikipedia.org/wiki/Cell_nucleus

    The nucleolus is the largest of the discrete densely stained, membraneless structures known as nuclear bodies found in the nucleus. It forms around tandem repeats of rDNA, DNA coding for ribosomal RNA (rRNA). These regions are called nucleolar organizer regions (NOR). The main roles of the nucleolus are to synthesize rRNA and assemble ribosomes ...

  4. Nucleoplasm - Wikipedia

    en.wikipedia.org/wiki/Nucleoplasm

    The organelles and other structures within the cytoplasm and nucleoplasm are organized by protein filaments within their respective compartments. The cytoplasm contains the cytoskeleton, a network of protein filaments found in all cells, while the nucleoplasm is believed to contain the nuclear matrix, a hypothetically analogous network of ...

  5. Nuclear organization - Wikipedia

    en.wikipedia.org/wiki/Nuclear_Organization

    NADs are associated with nucleolus function. The nucleolus is the largest sub-organelle within the nucleus and is the principal site for rRNA transcription. It also acts in signal recognition particle biosynthesis, protein sequestration, and viral replication. [36] The nucleolus forms around rDNA genes from different chromosomes.

  6. Nucleolus organizer region - Wikipedia

    en.wikipedia.org/wiki/Nucleolus_organizer_region

    Nucleolus organizer regions (NORs) are chromosomal regions crucial for the formation of the nucleolus. In humans, the NORs are located on the short arms of the acrocentric chromosomes 13, 14, 15, 21 and 22, the genes RNR1, RNR2, RNR3, RNR4, and RNR5 respectively. [1] These regions code for 5.8S, 18S, and 28S ribosomal RNA. [1]

    Police have asked villagers to check their bins for evidence after a 19-year-old man died following a stabbing. The victim, who was found injured in Station Road, Netley, shortly before 18:30 GMT ...

  8. Nuclear pore complex - Wikipedia

    en.wikipedia.org/wiki/Nuclear_pore_complex

    Nuclear pores are found in the nuclear envelope that surrounds the cell nucleus in eukaryotic cells. The nuclear envelope is studded by a great number of nuclear pores that give access to various molecules, to and from the nucleoplasm and the cytoplasm. Small molecules can diffuse easily but other larger molecules need to be transported across. [1]
