RNA Structure

• Ribonucleic acid (RNA) is a single, relatively short polynucleotide chain. Each nucleotide is made up of a ribose sugar, a phosphate group and one of four nitrogenous organic bases (adenine, guanine, cytosine or uracil).
• One type of RNA transfers genetic information from DNA to the ribosomes. The ribosomes themselves are made up of proteins and another type of RNA. A third type of RNA is involved in protein synthesis.
