Ribosomes are small structures found in cells that make proteins, which are essential for the body to function properly. They follow instructions from a molecule called RNA to put amino acids together in the right order. Amino acids are the building blocks of proteins, and the proteins created help the body grow, repair tissues, and perform many vital tasks like fighting off germs or speeding up chemical reactions. Ribosomes can be found floating freely in the cell or attached to another structure called the endoplasmic reticulum. Their role is crucial in keeping the body healthy and functioning well.
