4. What is the function of DNA?

The main role of DNA in the cell is the long-term storage of information.

The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code.

To read the genetic code, cells make a copy of a stretch of DNA in the nucleic acid RNA.
