DNA is the molecule that stores the genetic information a cell needs to produce proteins. But DNA is more than a long chain of genetic information; it has a carefully organized structure, and that structure allows a large amount of DNA to fit inside a cell.

Nucleic acids are important biological molecules that contain genetic information and help cells carry out their functions. DNA and RNA are the two main types of nucleic acids, and understanding how they are built helps us understand how they differ and what roles they play.
