Nucleasome
Nucleasome is a macromolecular complex that degrades mRNAs into nucleotides. Like Proteasome it exhibits a barrel-like architecture that appears to have evoled to restrict substrate access and prevent indiscriminate degradation. Formerly this macromolecule is designated as "exosome". Particularly, because exosome is also defined as "a vesicle excreted by mammalian cells" - Exosome (vesicle), and the similar barrel-like structure that degrade peoteins is named proteasome, it is reasonable to name the "nucleotide chain degrading machine" nucleasome. == Discovery == The nucleasome was discovered in 1997 by Mitchell et al.
