- 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.
