DNA

DNA types

• In eukaryotes such as plants and animals

  • nuclear DNA
    • great majority of DNA is found in the nucleus
  • Mitochondrial DNA
    • Mitochondria, organelles that harvest energy for the cell
  • chloroplast DNA
    • chloroplasts, organelles that carry out photosynthesis in plant cells

• In bacteria and other prokaryotes

  • nucleoid
    • most of the DNA is found in a central region of the cell called the nucleoid, which functions similarly to a nucleus but is not surrounded by a membrane.
