What is RNA?

Ribonucleic acid (RNA) is one of the three basic macromolecules that are contained in the cells of all living organisms. It is composed of a long chain, each link of which is called a nucleotide. During transcription (in the cell nucleus), nRNA chains are formed that ‘mirror’ an exact part of DNA, allowing the further synthesis of encoded proteins. This process is followed by translation, that involves another two types of RNA: tRNA and rRNA. The RNA macromolecule basically serves as a messenger between the nucleus with DNA and the cell as a fabrication station of proteins.
