Plasmids can be transferred between bacteria, allowing for rapid adaptation and evolution in microbial communities. By sequestering the master copy in the nucleus, eukaryotic cells can tightly regulate gene expression.
Organelle DNA: Echoes of Ancient Bacteria
Certain organelles that originated from ancient symbiotic bacteria retain their own small, circular DNA molecules. This manual, known as deoxyribonucleic acid or DNA, dictates how an organism grows, functions, and reproduces.
This mRNA then exits the nucleus and is translated into protein by ribosomes in the cytoplasm, linking the genetic code to the machinery of life. Plasmids: Extra Genetic Elements Beyond the main chromosome, many bacteria also contain smaller, circular pieces of DNA called plasmids.

This intricate packaging allows meters of DNA to fit comfortably inside the microscopic nucleus. Like mitochondria, they possess their own chloroplast DNA, which is passed down maternally in most flowering plants.
