Ribosomal RNA (rRNA) is a type of molecule and a key building block of the ribosome, the cell's protein-making machinery. rRNA accounts for much of the RNA in a cell, and it's crucial for life. It's ...
Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients ...
Neurons have a "hibernation mode." Scientists discover how brain cells use RNA tentacles to lock their protein factories together to survive when energy is low.
