    • What do eukaryotic cells contain?
      Linear DNA molecules that exist as chromosomes- thread-like structures each made up of one long DNA molecule
    • Where are chromosomes found?
      In the nucleus
    • What is the DNA molecule like?
      Very long, so it must be wound up so it can fit into the nucleus
    • What is the DNA molecule wound around?
      Proteins called histones
    • What do histone proteins also help to do?
      Support the DNA
    • How is DNA stored|?
      • DNA wound around histone proteins
      • DNA and protein is then coiled up tightly to make a compact chromosome
    • What also have their DNA?

      The mitochondria and chloroplasts in eukaryotic cells also have their own DNA
    • The mitochondria and chloroplasts in eukaryotic cells also have their own DNA - what is this DNA LIKE?

      Similar to prokaryotic DNA because it is circular and shorter than DNA molecules in the nucleus. It is NOT associated with histone proteins
