ribonucleic acid (RNA)

Ribonucleic acid (RNA) is a molecule that plays a crucial role in how cells function. It acts as a messenger, carrying instructions from DNA—the cell's genetic blueprint—to make proteins, which are essential for the body's structure and activities. RNA is similar to DNA but is usually single-stranded and contains a different sugar and base. It helps translate genetic information into the production of proteins and can also have other roles in regulating cell processes. In sum, RNA is vital for turning genetic instructions into biological functions within living organisms.
