What is a nucleic acid?

Nucleic acids are the polymers formed by a series of linked nucleotides. DNA and RNA are the two most important types of nucleic acids for life as these are the molecules that carry and transmit our genetic information. In humans, DNA is found in the nucleus of our cells, and a complete copy of the genetic information is actually contained within each individual cell. That means we each have about fifty trillion copies of our genetic information in our body! RNA is made by enzymes called RNA polymerases, which are responsible for transcribing the information from DNA into a strand of RNA, where it can move about the cell to carry out its function.
