What is RNA?

All modern life on Earth uses three different types of biological molecules that each serve critical functions in the cell.  Proteins are the workhorse of the cell and carry out diverse catalytic and structural roles, while the nucleic acids, DNA and RNA, carry the genetic information that can be inherited from one generation to the next.
RNA, which stands for ribonucleic acid, is a polymeric molecule made up of one or more nucleotides. A strand of RNA can be thought of as a chain with a nucleotide at each chain link. Each nucleotide is made up of a base (adenine, cytosine, guanine, and uracil, typically abbreviated as A, C, G and U), a ribose sugar, and a phosphate. 
The structure of RNA nucleotides is very similar to that of DNA nucleotides, with the main difference being that the ribose sugar backbone in RNA has a hydroxyl (-OH) group that DNA does not. This gives DNA its name: DNA stands for deoxyribonucleic acid. Another minor difference is that DNA uses the base thymine (T) in place of uracil (U). Despite great structural similarities, DNA and RNA play very different roles from one another in modern cells.
