Although most DNA sequences encode information that is used to make the proteins that travel throughout cells, some sequences are only intended to make proteins that stay inside the nucleus and monitor the DNA itself. These sequences often serve as binding sites for special regulatory proteins that manage the process of transcription.
Traits as diverse as the color of a person's eyes and the scent of a rose are determined by the information contained in DNA. Learn how this information is coded by strings of molecules called nucleotides.
