nucleus structure

Cards (16)

  • What is the main function of the nucleus in a cell?
    The nucleus houses the cell's genetic material and controls gene expression.
  • What are the key components of a cell's nucleus?
    • Nuclear Envelope
    • Nuclear Pores
    • Nucleoplasm
    • Chromatin
    • Nucleolus
  • What are nuclear pores?
    Nuclear pores are openings in the nuclear envelope that regulate the passage of molecules into and out of the nucleus.
  • What is chromatin?

    Chromatin is the complex of DNA and protein that makes up chromosomes in the nucleus.
  • What is the nucleolus?
    The nucleolus is a structure within the nucleus where ribosome synthesis occurs.
  • What is the nucleoplasm?
    The nucleoplasm is the semi-liquid material that fills the nucleus.
  • What is the nuclear envelope?
    The nuclear envelope is the double-layered membrane that surrounds the nucleus.
  • How does the structure of the nuclear envelope contribute to its function in regulating nuclear transport?
    • The double membrane barrier prevents free passage of large molecules.
    • Nuclear pores act as selective gateways, allowing specific molecules to enter and exit the nucleus.
    • Protein complexes at the nuclear pores regulate transport based on signal sequences.
  • Which organelle is the primary storage site for genetic material?
    Nucleus
  • What protects the nucleus?
    Nuclear envelope
  • What is the control center of eukaryotic cells?
    Nucleus
  • What does the nucleus contain that is essential for cell function?
    Genetic material (DNA)
  • What protects the nucleus?
    Nuclear envelope
  • What are nuclear pores used for?
    Controlled entry/exit of substances
  • What is chromatin made of?
    DNA and proteins
  • What is the function of the nucleolus?
    RNA production site
