Ribosomes

Organelles found in both prokaryotic and eukaryotic cells where proteins are synthesized.

RNA

Ribonucleic acid, a molecule essential for coding, decoding, regulation, and expression of genes, acting as a messenger carrying instructions from DNA for controlling the synthesis of proteins.

Protein

Large, complex molecules essential to all living organisms that are involved in virtually every biological process, including structure, function, and regulation of the body's tissues and organs.
