1. Researchers have recently identified a previously unknown compartment in mammalian
    cells named ‘exclusome.
  • Exclusome is a newly discovered organelle in mammalian cells.
  • It is made up of DNA rings known as plasmids.
  • It is located within the cell plasma.
  • This is peculiar because eukaryotic cells (cells with nuclei) usually keep most of their
    DNA in the cell nucleus, where it is organized into chromosomes.
  • Instead, in the exclusome, it is organized into plasmids -small, circular DNA strands that
    can replicate independently of chromosomes and are usually found in bacteria and other
    microscopic organisms.
