New Trick Found for How Cells Stay Organized

Johns Hopkins. US: Ribonucleic acid, or RNA is one of the three major biological macromolecules that are essential for all known forms of life (along with DNA and proteins). RNA granules are tiny cellular compartments that are not bound by membranes like most other compartments. They were thought to not need a physical boundary, but they do. The boundary is a new type that resembles an irregularly shaped protein cage that revolves around the contents of the granule.

RNA Society: Ribonucleic acid, or RNA is one of the three major biological macromolecules that are essential for all known forms of life (along with DNA and proteins). A central tenant of molecular biology states that the flow of genetic information in a cell is from DNA through RNA to proteins: “DNA makes RNA makes protein”.
