If you’ve ever sat through a high school biology class, you’ve likely learned about the essential organelles that make up a cell—structures like the mitochondria, which produce energy, or the nucleus, which houses DNA. Traditionally, these organelles were understood to be membrane-bound compartments that each performed specific functions. However, this long-standing view of cell organization has been upended by an exciting new discovery: membraneless organelles, or biomolecular condensates.
For years, scientists believed that all cellular structures needed membranes to define their functions and keep everything in order. But in the mid-2000s, this theory was challenged when researchers began discovering that some organelles don’t require membranes to operate. These membraneless organelles, made up of proteins and RNA molecules, can form gel-like droplets inside cells that function as distinct biochemical compartments.
