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.
