Ribonucleic acid (RNA) is a polymeric molecule that is essential for most biological functions. RNA can perform functions itself or form a template for the production of proteins. There are four types of RNA: Messenger RNA (mRNA): Carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm. Each mRNA molecule encodes information for one protein. Transfer RNA (tRNA): A small RNA molecule that plays a key role in protein synthesis. tRNA serves as a link between the messenger RNA (mRNA) molecule and the growing chain of amino acids that make up a...

Regulatory RNAs are RNA elements that regulate expression of downstream genes. They do this by binding to cellular metabolites that cause a “switch” in their structural conformation.
