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.
